Hello GOOD Folks !!
I have a 2002 Taurus with the Duretic engine with 43000 mi on the clock. When I turn on the AC, every once in a while I can feel the car missing as in not fireing on one cyclinder? It was only when I have the AC on when at a light at idle. Now every once in a while, with the AC off, I can feel the same miss?? I was wondering ( since I here so much about what the MAF ) senser does, If that Maybe that is my problem.
Thanks for any suggestions you guys may have?

I don't think the MAF would cause a misfire unless the MAF's intermittant. I'd look more at plug wires (or does your car have CoP?) and add a bottle of fuel injector cleaner to the tank.

If you have access to a scan tool that can read the component parameters, check them for misfire counts on the individual cylinders to see if one particular cylinder is reporting misfires.

Thanks as ALWAYS Rod!!!!!!!. Now I never thought about plug wires and I have had this car for a long time. Think I will take your advice aand get a new set of plug wires !
Thanks again for ALL the help we all get you this list !!!!!
