I have a 2002 Ford Taurus. A couple weeks ago my Heater Assembly cracked and caused my car to over heat. Well we replace the heater assembly and my check engine light is on and every time i am at an idle the car acts like it wants to die. We had someone tell us that the #1 was misfiring. We have changed the spark plugs, wires, ignition coil, #1 fuel injector, EGR Valve, EGR selnoid. There is absolutely nothing leaking from the car. We have no idea what else to try.

It's still setting a misfire code for Cylinder #1. If you have already covered the plug, wires, coil and injector, you'd better do a compression test next. I would also check for injector pulse with a noid light and spark with a spark tester at that cylinder to make sure they are both present.

My husband did the compression test and thought it was fine. I will double check. Also, he said everything is getting spark.

I think he needs to start over and check everything again. Something has to fail or it wouldn't be misfiring.
