When was the last tune up? Have you checked for vacuum leaks? Has the check engine light come on to identify which cylender is missing? Have you checked to make sure none of the spark plug wires are arcing / shorting out on the engine and they are all on the plugs tight?

Let me know.

Hello Joe thank you, I had replaced the spark plugs and the t.P.S at the time of this question being asked, and had purchased a 55.00 coil pack, but instead of replacing the coilpack, I first put on an economy (20.00) set of plug wires and it is now perfect. Thanks again. Mike

Great! That is a common problem. THey break down from heat and end up arcing and causing a miss. Glad it's fixed. Let us know if you have questions in the future.

Happy New Year and thanks for using 2carpros. Com.
