Is the check engine light on? Does it start and run normal until it's warmed up?

Check engine light is on. The car runs fine when its warm OUTSIDE!

Have the CHECK ENGINE light DIAGNOSED. Don't put parts on because of a code. Have the cause of the code determined. Possibly faulty coolant temp sensor or problem in that CIRCUIT (wiring , connection(s) or low coolant) , or several other possibilities.Parts places SELL PARTS they don't diagnose---just my opinion...Good luck.
