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

    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.
