Someone help me please..

[Mr_Legacy]

well where the hell do i start? first off i have a 95 subaru legacy l with a 2.2L, i was readin from a past post on here where someone said to clean your a part to my engine, i think its (ivac or iavc) well i cleaned it out an got all kinds of curd an build up outta it.

but now its still been sluggish, than gain power an goin back below 500 rpm, it shuts off an than starts backup but when you start to give it gas it doesnt act like anything is gettin to it.

I put a bottle of sea-foam in the gas tank so i hope that works.

Can anybody tell me what the f*ckin problem is. I have busted many knuckles an tore up my hands to find the problem an nothing so far has came to my attention. [please someone help me]

[Airgne]

wow im sorry please speak clear next time. had to read 2x. start with a tune up, and a bottle of sea-foam threw the pcv valve. it will smoke, but its just the carbon and nasty crap coming out.

once again do a tune up on it.

[green97gt]

you done the basic tune up?

FUEL filter?
air filter?
plugs?
wires?
etc?

start likin those busted knuckles dude! :smt026

[Mr_Legacy]

sorry i have two little girls that were pushin keys while i was tryin to type. yes i have done the basic tune up, the air filter, the spark plugs, the wires etc. an i love busted knuckles but when you can find the problem it starts to get alittle overboard.

[Airgne]

been working on cars for 12 yrs and aircraft for 7 yrs get use to the knuckles. go in to more detail about what it is doing. try the sea-foam threw the intake.

[green97gt]

fuel filter want on that list.

is those get restricted, it wont get enought gas to the motor to maintain higher RPMs

[Mr_Legacy]

sorry about the confusion so here is what it is doin.

when im driving the vechile or while its sitting an idleing, i try to push on the gas an it hesitates. (while im driving) It wont go an i have the pedel to the floor, (it chugs like nothing is gettin thru the line) than sometimes it takes off an does it again. Goin up hill or down shifting to make it up the hill the car will sometimes chug an than cut off in mid strem of climbing up the hill. I have cleaned the pcv valve with q-tips an looked at the iacv valve. i added a can of sea foam to the intake an thru the gas tank. im hopin this works.

[Mr_Legacy]

i dont remeber if i replaced the fuel filter or not. i have replaced the spark plugs, the oil filter, the wires an etc..

[j_saffron]

FUEL filter? :smt026


fuel filter want on that list.
if those get restricted, it wont get enought gas to the motor to maintain higher RPMs


change the fuel filter. its cheap and easy. if you cant remember, do it again.
if that doesn't do it, could be fuel pump.

cutting off and bogging down is either not enough gas or not enough air.

if you have changed the fuel filter and it runs great for awhile then acts up again, could there be rust in the gas tank?
shouldn't be with a 95 but if it sat for a year or two, you never know.

inspect the old fuel filter pour and shake it out over a 5gal bucket, and look for rust particles innit.

[green97gt]

yup, do the fuel filter. its quick and easy

on my 97 it is located on the drivers side(your in the states right?) of the engine bay, attached to the strut tower.

i would imagine it is the same for your 95.

[Airgne]

also use good gas. dont use arco or 7 11 gas. use prem gas for sometime and see if it changes.

[Mr_Legacy]

okay so i just went to advance auto parts an bought a fuel filter..it seems to run alittle bit better but does bogg out once an awhile. I'm gonna try to get the rusted bolt off the injector cover to check an see if the injectors are bad. I'm sure they havent been replaced because both of the bolt (on the left side of the cover) are stripped an i know that they havent been taken off..so anybody else have any advice? (thanks to all that are helpin me figure this piss off of a problem)

[green97gt]

before you do that, remove your old fuel filter... shake it out into a bucket,see if its full of crap... if you want you can even run alcohol/water thru the old filter to see what comes out.

if an injector is BAD it will not function at idle either, but it may be that the screens in there are dirty as well and not pass the amount of gas needed for higher RPMS, but if that is the case, i would imagine your fuel filter would be nasty.

i just dont like playing with the injectors on these cars cause i have a habit of screwing up the O-rings on them.


what do you mean bog out? like, you press the gas and it RPMs dont change? or the car dies? or?

also, do you think your running rich or?

the more info the better.

[Mr_Legacy]

well lets just say that when i press on the gas that the rpms pretty much dont go anywhere, than all of a sudden outta no where the car takes off like a bat outta hell. we are gonna take the old filter out an run the water/alcohol thru it an see what comes out. I have a friend that says it could also be the catalytic converter, im not sure this is why im askin people on here.

[jey]

Check for vaccuum leaks.

[green97gt]

yeah, get some carb cleaner or other arosol spray can, TB cleaner, etc. spray it around the motor while it runs at idle. if the motor starts coughing, youve got a vacuum leak in that area.

if it was a clogged cat the car wouldnt ever go like a bat out of hell. so i doubt that...

EDIT: are you sure your throttle plate isnt sticking or something? have you checked that out? take off your plastic air intake tubing and look into the throttle plate as you open it manually, make sure that isnt all gunked up as well.

when you start the car what RPMs does it sit at? just turn the key on and let it run for a bit...

for instance, mine starts out at about 1100 rpm for about 30 seconds, then goes down to 7 or 800 rpm

[Mr_Legacy]

i havent checked for vaccum leaks. an i have cleaned my throttle body. an when i start my car it sits at 1000 rmp than goes down. so i defently should check for some vaccum leaks.

[Mr_Legacy]

okay so once again im havin a problem. I have replaced the fuel filter an have had a tune up done also. the car doesnt seem like it wants to run. Just about 20 mins ago I was driving around an the car decides to just wont to "bogg" out. idk if i have a vaccum leak problem or a idle control module or anything. I took it to advance an the code came back as an idle control system ( i have no idea what the hell that is) so im in the same spot i was before. its really startin to be a money pit

[green97gt]

wanna sell it? ill give you $100 for it.

by "bog out" do you mean start choking? or the motor shuts off?

did you make sure the hose coming off the IAC is connected securly to the plastic intake piping?

cause if there is an airleak on the iac it will not want to idle or run right.

what specific code did it bring up?

[Mr_Legacy]

at this point i wouldnt care what happened to it, but its my fiancee's car an im sure she would get mad..an yes by boggin out i mean the engine is choking..choking on something bad..an yes i made sure that the hose coming off to the iac is connected but it seems to still be doin the same thing. an the specific code i got was a "idle control system" an the guy at advaced said that it has to do with my idle system module..so im hopin on gold bricks that someone can help me with the problem

[green97gt]

if you want help ya gotta give us details bro.

P0505 *Idle Control System Malfunction
P0506 *Idle Control System RPM Lower Than Expected
P0507 *Idle Control System RPM Higher Than Expected
P0509 *Idle control system circuit high input
P1511 *Idle Air Control Solenoid Signal 1 Circuit High Input
P1512 *Idle Air Control Solenoid Signal 2 Circuit Low Input
P1513 *Idle Air Control Solenoid Signal 2 Circuit High Input
P1514 *Idle Air Control Solenoid Signal 3 Circuit Low Input
P1515 *Idle Air Control Solenoid Signal 3 Circuit High Input
P1516 *Idle Air Control Solenoid Signal 4 Circuit Low Input
P1517 *Idle Air Control Solenoid Signal 4 Circuit High Inp

which code did it throw?

have you unplugged and cleaned the connector?

have you removed the IAC and cleaned it?

have you done the "carb cleaner spray trick" to look for vacuum leaks? or a possible bad IAC gasket?

[Mr_Legacy]

it threw up the code p0505..an yes i have unplugged an cleaned both..an what is the carb cleaner spray trick?!? i have a.d.d so its kinda hard to describe what is goin on with the car. im tryin to think an put into words but doenst come out right.

[green97gt]

get a cheap can of spray carb cleaner from the parts store, start the car and open the hood, then spray it around the engine slowly, in various spots.. if you have a vacuum leak, or bad intake/throttle body/iac gasket of some kind, the engine will choke. its a way of locating your leak/issue.

this code must be setting off the check engine light right?

the "clean your MAF" advice is way overused, but ive noticed with subarus it is very important, have you cleaned you Mass Air Flow(MAF) sensor?

get the right can from the store and you can use it for both cleaning the maf and finding vacuum leaks.



when i first bought my subaru i had alot of trouble with stupid issues like this, untill i just broke down and replaced all the rubber hoses, vaccum lines, and anything attached to the plastic intake piping.

also, it is possible your IAC is bad. youve located it right? cleaned it?

your IAC is basically a solenoid, so try doing this... turn the key on to the run position, turn your AC off so the fans shut off etc, then listening carefully turn your throttle plate from idle to Wide Open Throttle(WOT) you should hear your IAC click on and off when you get just off/on idle its a small sound, but it is there.

if it is clicking your electric circuit must be working, but it may be catching.gummed up.

if you cant hear it, try using a socket extension and putting one end on the IAc and the other up to your ear.



that was long winded. just tryin to help.

good luck.

if your out of ideas, maybe take it to the dealership and have them diagnose it, and if your familiar with a wrench you can to the replacements yourself.

[Mr_Legacy]

thanks alot man. i have been tryin to find out the problem to this damn problem forever. i have cleaned the maf with a cleaner like a million times. but i dont think that is the problem. im gonna use that can i have to pretty much check for leaks. an i will checkin of the iac an all too. i will give ya an update to what i found.

[green97gt]

when you do take apart the iac to clean it etc, its kind of a pain in the ass.

but when you got it apart, do the throttle trick and see if it clicks up and down, or in and out, or however you want to put it..

and buy an iac gasket before you do it, cause you will most likely destroy the one thats on there when you remove it.

[jey]

The IAC itself could be dead if you've already tried cleaning it and checked all the hoses going to it.

[Mr_Legacy]

okay so i have taken a video of what the car is actually doin, since im having a hard time givin details on exactly what the hell the car is doin, if you watch the video your gonna have to turn the sound down about half way due to the echo from the garage where the car is stored. the sound it makes is what it does when you step on the gas or better yet put it in gear to move the car. im sorry about the language but I was really pissed because I have fought with the car for over 2 weeks now. here is the link to the video..thanks everyone for their help..

http://www.youtube.com/watch?v=x6wlOEhgb0s

[Mr_Legacy]

so i posted a video to show exactly what was goin on, someone please get back to me on what is wrong with the car. the video link is above an you might have to turn down your volume down just alittle bit due to the echo from the garage where the car is stored. thanks everyone

hmm bad EGR? I had a 98 forester that had a failed one.. not only did it take about 6 seconds of cranking for it to finally start the idle was erratic as well.

The EGR is supposed to be closed at idle, but if it is stuck partly open then idle quality will be poor

Your standard EGR..

[Mr_Legacy]

okay so i looked online (on google) to see where the egr valve is? well it has givin me different things instead of what i needed to see..can anybody give me a link that can show me exactly where the egr valve is?
