Not sure if this picture looks exactly like your engine but give it a shot.Bill thanks for the response, I did mean 3.8l and the engine light has not come on so I assume there are no codes. Prior to the problem, I did clean the PCV valve so that might have caused the problem I guess. I am going to inspect the PCV hose as suggested. Can you tell me where the idle speed control motor is located? Thanks again for your help.
