Engine will not idle (intermittent), but will restart immediately. NO check engine light. I have looked for vacuum leaks but can't find any. This happens for a week or so then is okay for awhile. Then the problem re-occurs.

When it first occured, I put a can of "Seafoam" fuel injector cleaner in the fuel tank then drove it for about 400 miles. This did not help.

Please help!

Thanks,

-John

Check the idle air control motor, throttle position sensor and the coolant temperature sensor to include the EGR

I agree with RASMATAZ, it sounds like the IAC valve is dirty or needs replacement, this guide can help you as well,
