Momentary stumble after prolonged slow/stop/go
OK, I have an intermittent problem that occurs after driving in stop-n-go traffic.
After 10 minutes or more of stop and go, moderate throttle will cause a serious stumble. Feels like a lean misfire on several cylinders. It clears itself after a few (10-15) seconds, and the car returns to normal.
During the stop-n-go, everything seems normal. Smooth idle, no off-idle issues. No codes are saved, and after the event, there is no other signs of trouble.
