Hesitation/Flashing check engine light
I have a 2001 Coupe with 30K miles. Recently I have been getting some hesitation, and sometimes accompinaied with a flashing check engine light. Any ideas? Would I need to do a de carb procedure with only 30K miles. The gas in AZ is pretty bad. Any suggestions? Thanks in advance.

When the flashing occurs, check the DTC codes in the DIC. Here is how you do it:

Most likley you will find that you are getting a PCM 0300 code = cylinder misfire.
Check your plug wires and plugs as stated above!
Please let us know what you find.
