I have 1995 sse N\A. When at idel the car shakes a little . So far I have chaged the spark plugs with delco plugs and Prospark wires. I have also changed the coil packs.
Please help me.............

make sure the rear wires with the boots are on good. When i put the boots on new wires, they were to long, and the plug and wire had a gap between it, and i could hear the spark everytime the cylinder fired, and it was idling bad.

Idle problems are almost always vacuum leaks. Check your hoses.
