This sounds like a problem i had, for awhile. I changed out all my spark plugs and the ICM (both) on top of the airbox. then put some seafoam in the car. smoked like all great out for about 5 mins and had to change the oil in like 200 miles but no more codes for me. I dont know if that helps at all but it did fix my problem. Also see if you get the codes cleared and got to a WOT in second the took off my check engine light for a day till it came back and i did the above. here is the link to seafoam your car

I drove the car today for about 100 miles ! and I dont think ill be driving it again till i run the tests on wed ! its misfiring horribly even at idle i can fell here and there rough no backfire but really rough and i cant push the car over 5 psi now !!!!! it acts like its sufficating the turbos ! Im affraid it gonna do more damage to the car! Please when u read this I dont want you to think that im pushing the car to break it,not knowing what Im doing ! I am a backyard mechanic almost always do my own work , learning and trying to provide the best symptoms way i can too u guys !



Ill defenatly look into that seafoam !

 

It's sounds like its running in limp mode. You definitely have a A/F trim issue from a malfunctioning sensor or a sensor thats getting false readings. You can try the seafoam but I don't think that's going to fix it. What codes are you pulling now?

edit: misspelling

 

won't know till wednesday ! i can hardly sleep , I hate waiting to see whats wrong with something !

 

yea, i would also say go back to stock spark plugs if you have not and you could also have to replace your coil packs. This sucks man, hope the seafoam helps with the new plugs and then i guess go for coil packs, and the ICM.

 

let me know what you think of this ! as we were doing a boost leak test, found only minor leaks in the aftermarkt DV's he pulled the oil dipstick and oil shot out???? I was not there for that incident but he xplained . we also ran vag and its showing consistant mis fires in number 6 cylinder ! also 1 3 & 6 ,we swapped the Coilpacks and it did nothing but pull up the same codes.. I put in the stock DV's and there is no boost leak ! the oil squirting out was due to the Pvc vavle but highly doubt that causing the misfiring! no other codes except Misfires...........
