Replaced spark plugs, same problem. Replaced core packs, same problem, replaced max air flow sensor. Same problem. Car runs great, as long as you are moving when setting still, car shakes like it's going to turn off. Service engine soon light comes on. I can drive the car for about a hour or so and the service engine light will turn off and car seems normal until you let it idle for about ten minutes, then it will act like it going to turn off and service engine light comes back on.
Do you
have the same problem?
Yes
No
