I have a 1992 saturn sc2. The car seems to run fine driving down the road but when stopping the idle falls very low and then catches back up. It also idles rough can't really feel it sitting in the car but you can see the engine shake when you look at it idle. It also has whit smoke after the engine has idled about 15 minutes then reved up. I have replace the radiator, plugs and wires, changed the oil and filter added fuel system cleaner. Any help would be appriciated. Thanks.
have the same problem?
