Is your problem still the miss at idle?

you may require an adjustment on the throttle plate sensor . the two inserts on the side can be pried out and under it will be 4 screws . mark the orignal position for reference and the adjust about 2 millimeter on the up side then on the lower side .test in each position

hope this will help.

Thanks guys for your input.

I am going to assume your issue is fixed.

For others having this nagging issue.

* I suggest you give the throttle body chamber and Idle Air Control Valve a good cleaning.

* The signal to start - run the fuel pump goes through the OVP relay, which has been superseded due to random thermal failure issues.

* The fuel pump relay has on many models been superseded three times due to random thermal failure issues.

* The Crank position sensor can experience thermal failures that match your symptoms.

* Try measuring system voltage, perhaps the charging circuit or battery is so weak that it can't operate the electronics correctly. Failing batteries cause no end of havoc, and the notion that just because it took a charge and started the car must mean that the battery is good is false. Test it to be sure

Here are some rather odd issues that have happened to me many times, and could match your symptoms.
