okay, im taking my car to a shop up in palo alto. I am having my intake manifold gaskets fixed( hopefully to cure my rough idle once the enginge heats up) Is there anything else that i should have looked into that any of you guys have had done to your cars? Please give me your info? Also a few weeks ago i had all new spark plugs, wires, belts, and hoses put on, so that area is ok. Thanks, Gerald Williams 1990 M3
