Misfire.. What kind of misfire? Describe what happens.

Vibration.. Prop shaft centre bearing?

ordered the bearing from GT500 today already. but i tried to move it with hand and it looks ok...
misfire it just if i put my foot down its starts going rough, even on the motorway if im going up the hill so it gets more load, starts missing the fire... sparks has been changed as well as coil pack (second hand) map sensor as well

ive changed the coils already, but that didnt helpet
vibration:
it only feels when the after few miles of driving. and even when im accelerating slowly, and on 3rd gear i can feel it just a little bit... its just feels that the whole car is shaking

[DamianURS4]

shaking could be sub-frame related but details will help identify your root cause.

Have you got any local audi mates that you can swap coil pack with? With regard to the shaking, are you talking about through the whole gear, just after letting the clutch out, different behaviour through the rev range - can you be a little more specific (as I have possibly been there!!).

[spink]

misfire is probably a bad spark plug/coil boot/coil or wiring to the coils

whereabouts does the vibration feel like its coming from?

springs are on their way to you

thats what i think as my urs4 p*****g me off now. ive got a misfire, cant find the problem on that. then after the last weeks front suspension replacement i realised my car is vibrating badly on 2nd gear and a bit on 3rd. an yestarday one of the springs snapped off...
gyus have you got any tips or ideas what could be with the missfire and that vibration?
please help!!!!!!!!!!!!!
