Nevermind I think I found the problem. It appears to be a bad connection on my #2 coil pack. Seems to be idling okay for now. Still would appreciate any input. Bye for now Cindi

Depending on miles, if you have a v6, the spark plug wires are known to fail around 55k-85k miles. Also engine mounts would cause a rough idle when worn and leaking. Bad spark plug wires would eventually cause a check engine light and engine mounts usually wont. Hope this helps
