Title: Misfiring/Hesitation
Post by: salsheikh on 02 March 2011, 12:29

guys, I have a 1.8t AUQ engine and my car is having a misfire/hesitation issue when it gets near 3000rpm. the car feels like it is struggling a bit when it happens and drives ok until that point.

I also notice that the exhaust smoke smells of fuel ...

any ideas???

does your car have coil packs? sounds like one or 2 is away

MAF sensor. Disconnect it and drive on a short journey. It may cut out but if it stops hesitating, thats yr culprit.

Any fault codes?

As said could well be coilpack,MAF, Or lambda sensor.
