Hello boys ive posted before about my misfire issue, long story short ever since i changed my plugs a few month ago (changed from ngk pfr6q to the same new pfr6q plugs) whenever the car hits a decent anount of boost the car misfires or hesitates/whole car vibrates rapidly you can feel it in the peddles and wheel, i changed back to my old plugs to see if it was them new plugs, no change so i know its not the new plugs, i had a friend scan for codes and only one code related to the EGT sensor came up so we changed that and no difference the same issue persists, next ive ordered a new MAF sensor and installed that today and still the problem persists (changed MAF as when unplugged nothing changed, the car ran exact same and not even EML came on so i assumed it was faulty MAF) only thing i have left to try is all new coils, but we never got codes related to them but ill check them anyways when i can get my hands on a set that i know work.
In short im stuck and dont know what todo next, the car has a pretty lumpy idle now but it never used to when i first got the issue, car runs and still pulls fine until you make enough boost for it to hesistate, we tried driving with the MAP sensor unplugged and no difference there either, ive yet to have a VCDS scan the car as i dont know anyone that has one unfortunately but any adivce would be greatly appreciated, its frustrating not being able to enjoy my money pit lol.
