[s-cars] Urgent.. UrS4 vibrates when turbo should kick in...

[Ivan Demkovitch]

Folks,

Small update:

Replaced plugs, fuel filter, air filter and oil :)

Seems like car drives better now and I didn't expierence any surges since 
then. Don't know what contributed though. However I still don't like 
something about the way it accelerates. I can hear some kind of "kick" in 
tranny area when I lift of pedal on high acceleration. Driveshaft, and diff 
mounts are ok..
