Ok so i was getting a check engine light for my coolant temp sensor. So i went ahead and ordered a blue coolanbt temp sens put it in. Car seemed to run perfectly fine for a little while and all my engine codes disappeared. Drove for about 10min and i noticed my car starting to sputter on giving it gas... OOPS another check engine light... after obding it i found it was p0302 cyl 2 misfire .. cleared the code .. it kept coming back .. ONLY THAT Cylinder. I changed all wires, brand new plugs, swapped injectors... and also checked coil. Everything seems to be working fine.. EXCEPT IT STILL MISFIRES... then later replaced all vacuum lines... STILL MISfiring. Noticed that it only misfires when car warms up... when car is dead cold .. runs fine... after coolant gauge hit above C/Cold ... it starts sputtering. Didnt misfire when the coolant temp sens was dead and showing always cold. ANY SOLUTIONS ... are the coolant temp sens and misfiring related???? Someone please help ANY IDEAS ARE GREATLY APPRECIATED.. THANKS SOO MUCH!!!

Ok, 1. What model year and engine do you have? That's *very* important if you want our help.

2. You said wires, so I assume you have a V6 then, no?

3. Did you read our FAQ and search our archives with your P-code? I bet you'd find a TON of information on it.

done - second as Nate said search using your P code and you'll get some information on your issue.

Your ignition coil might be the culprit then.
