I'm gonna be the first to chime in and give the token "dirty MAF" advice.

I thought the same thing, i cleaned the maf sensor with a cleaner that was supposta work but it still does the same thing. i sparyed it like 10 times like the bottle said but it defently could be a faulty maf sensor. i will check into that..

try disconnecting the EGR valve vac line and plug it with a screw and see if it goes away if so u got a bad EGR

so here is an update, i took it to advanced auto an they ran their engine code check an it came back as a idel system, I'm wondering if anybody has ever heard of this an how do i fix it..the car is running better but the check engine light is still on. Someone please let me know what I should do.

You could try cleaning the IAC valve.

Also, I'm pretty sure this thread isn't in the appropriate section :smt006

Did this start happening the ride right after you replaced the plug and wires?

If you have a check engine light then take it to a Subaru dealer and have the codes read. Repair the codes then see if it runs better. You really can not shortcut engine codes and hope to make it run right.

He already got the codes read.

Yes, he did. However, the answer he got seems quite vague...

Go to a dealer and get the definitions as well.

Do you know the exact code numer(s) that came up? If this is OBDII ('96 or later,) it should be. The following codes that deal with the idle system might help you determine what's wrong.

P1501 Idle Control System Malfunction (Fail Safe)
P1507 Idle Control System Malfunction (Fail Safe)
P1510 Idle Air Control Solenoid Signal 1 Circuit Low 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 Input
