View Full Version : No boost and need help with vacuum diagrams and AT oil light

Cant seem to find a good vacuum diagram for a 95 2.2. Im looking for how all the stuff on the passenger side of the engine bay hooks up. There is a valve under the intake manifold with 2 ports on it and there are two vacuum ports on the intake manifold right above that. Then there are 2 valves on the passenger side engine bay that hook to each other. If anyone can explain to me how all these hook up it would be greatly appreciated.

The other problem Im having is that I can not get boost :cry: . At idle Im sitting steady at about 21HG. I rev all the way up to about 5k and I dont even get close to 0HG let alone boost. I dont hear any big air leaks and I cant imagine that it could be that big of an air leak. Right now the engine isnt tuned very well(Im sitting at about 10.2:1 AFR at idle). Im going to check the bolts on my exhaust manifold in the morning and make sure there are no leaks.:roll:

One other question, I never drove the car since the engine was shot when I bought it, but when I first start it the AT oil light flashes quickly for about 5 seconds and then turns off and doesnt seem to come back. Is this normal?

mine does that. i believe it has something to do with the transmission.. atleast thats what mine says in the owners manual.. is yours automatic or 5spd? i know it doesnt do it unless there's a problem.

Flashing AT light usually means low fluid, or the temp is out of range... my car would do it on cold startup in the winter. No problems during warmer months.

Its probably low because some spilled out, I will top it off and see if it fixes the light.

Well, I took her for a maiden voyage around the block. It ran like poop but I did get boost and got the BOV to hit too. Runs like poo though, I need to figure out the vacuum line hook ups to fix the rough idle. I also have a fat oil leak coming from somewhere around the back of the engine. Its pretty bad.

Turns out I was looking at the oil leak and it was gear oil from my front diff(at transmission). There is quite a bit of crud around the passenger side axle where it goes into the transmission. Are those seals replaceable?

EDIT: Found out those seals are not replacable without removing the diff from the tranny and splitting it. I cant seem to find where the oil leak is coming from, but it is ALOT of oil. Im not sure if it is gear oil or engine oil. Im leaning towards engine oil. Could the rear main seal be that bad? Anybody ever have an issue like this?
