Check for exhaust for leaks! cracked exhaust manifolds, pipes leaking, the mixture maybe very rich at times from a malfunction...Have it read for codes, even if the check engine light is NOT on the computer will have stored information and codes. Discount auto stores will read codes for no fee. write them down.

I was told they have manifold cracks are under warranty but have looked on line with no luck I do know for sure they will replace the trans cooler lines for 1k under warranty lol
