Dealer can't fix rough idle?
I have an 09' Focus se. I've noticed that within the last 2 months or so I have had a pretty rough idle when stopped at a red light or traffic. When I apply gas the roughness or vibrations go away. Even when I turn on the A/C it helps. I've researched online and have seen some TSB's saying it could be some rear engine roll restrictor thing lol. I take it to the Ford dealer today and he said there is nothing wrong with it. They checked cylinders, motor mount, the engine restrictor, etc. He said its just a common problem with our cars and ford has no fix. QUESTION IS: Is this true lol? Anybody else have this problem and fix it?
Thanks a lot!
