audi s4 b6 engine shaking
Hi everyone,
I'm looking for some advice on my b6 s4, she has 126000 miles, is a 6 speed and recently i have been experiencing intermitted shaking. generally after a long drive after downshifting it starts to shake but only above certain rps (today was 2700) . The shaking feels like a misfire or the timing of the engine being off. we have checked the clutch, we changed the coil packs, spark plugs and fuel filter. any suggestions on what it could be? my dealer has no idea and ive tried about three different shops without success. after a few hours the problem goes away making it difficult to diagnose because if i wait to take it to the shop overnight the problem has sorted itself out overnight. Please Help!

There are no codes bieng thrown, we cleaned the sensors and checked the timing, my shop guy thinks it may be the flywheel , witch coincides with another post i have read here on audi world, ill call him and ask about the timing chain guide. its certainly an engine timing issue, thanks for the responses ill let you all know what we fix and if it works

From: CT
1: Coventry Motorcars in Coventry
2: NorthBay Imports in East Windsor.
Those are the only 2 places I bring my car to.
I have also heard good things about ICS Performance out of Stamford and Excelerate Performance out of Branford but I don't have any first hand experience with them.

2: NorthBay Imports in East Windsor.
