Hi, wondering if anyone can shine any light on this on going problem i have with my car. (2.0 fsi non turbo 150. 2004)
Basically when engine is running on light load i.e gentle throttle i can feel a slight hesitation. It can be seen by the needle also jumping around by 200-300 rpm. It only seems to show up when the revs are above 1.8k and engine has been running for 5 mins+ and will keep doing it until 3.5k ish. Also when holding the revs constant while stationary at around 2.5k the revs will just randomly drop down 200-300 rpm then slowly climb back up. I have replaced all the coil packs and this has not stopped it.
Changed fuel filter. Had diagnostics on it and no faults show up.
Dont no what else it could be?
Thanks in advance
