Idle surge and engine cuts out

Hi Pete,

Is the malfunction indicator light (check engine light) indicating? Have you had the vehicle checked for trouble codes? I would suggest starting with this. A scan would help in diagnosing the cause of the problem.

There are a few possibilities for such problems and one of it is a bad MAF. It can also be due to a faulty or dirty throttle body or the auxiliary air control valve.

Hey my friend. Thank you for the reply. This problem has been going on for awhile. At one time the "service engine" did come on but went off. While the problem continues the "service engine light has not come back on. After the engine light came on and went back off. I changed the oil and bought a new battery. Did disconnecting the battery erase the codes? Thank you again for helping me.. Pete

Disconnecting the battery would erase the memory (fault code) of the ECM and if problem does not recur, it would not show again. However, there are some fault codes that do not trigger MIL but would be recorded by the ECM.

Getting a scan done is still a good idea.

Try cleaning the AAC and throttle body to see if it makes any difference. By the way before you start with anything, ensure there are no breaks in the intake hose from the air cleaner to the throttle housing. Any air leak can cause havoc with the idling system.

Thank you a bunch buddy. I will start checking.

You are welcome.

Let us know how it goes and if you require further information or assistance, we are here for you.

Have a great weekend.
