Ok so from reading other posts with these codes it looks like I should change the coil packs, which I did. I am still getting the same codes and my car is still misfiring. I am almost read to say f it and sell my car, I'm getting a little tired of this bull.[:@][:@][:@][:@][:@]

Can some one please help

 

oh, I also cleaned the MAF thinking that would help, but it didn't. I have a 2001 1.8t so I don't think I have a ICM, correct me if Im wrong.

again please help asap

 

what about the plugs and ICU, all things that can go bad, and we recommend buiying one plug and switching out each one until it goes away, if it doesnt then its either a Plug checked to see if there fouled or the ICU

 

look at the list on the right it gives possible causes for those codes

thanks I'll try switching 1 coil pack at a time, if that doesn't work then i'll go buy new plugs. I noticed on the list it said MAF, before all these codes PO300,301,302,304 started I had a code of PO102 which was something to do with the MAF low input, which was a bad ground that i never did fix yet because this problem came up. Do you guys think I just need to get a new MAF sensor? and if so can I just buy the sensor or do I have to buy the housing with it? I did clean the MAF about 2 weeks ago and that did seem to help.

 

P0102 would explain a lot and no you cant buy just the sensor you have to buy the whole thing

Try
www.ecstuning.com
for the MAF. I bought a remanufactured one for $85 2 years ago,
and it's still running fine. Definitely change the plugs.I have the same
engine and use NGK PFR6 spark plugs.

 

update:

just replaced the coil packs and spark plugs. Only code that shows up now is PO302, and my car is still misfiring.

Whats else should I try? thanks again

 

you changed all the plugs and coil packs? did you just switch the coil packs round? P0302 is spark plug/coil packnumber 2 so change that coil pack with another and see if the code moves with it
