Gannon M asked:


Hey guys, I have a 1990 Audi Coupe Quattro and it’s been shaking at idle. I replaced the front left motor mount because it looked like it was the one that was vibrating, but after I finished the engine was still shaking. (The engine itself is actually shaking very slightly under the hood) What do you guys think it could be?
If it is a mount how do you find which one?

   It may need a tuneup, but if this started suddenly it usually is a vacuum hose leaking.
