My car runs normal with a normal idea when the Engine Light is off. When ever you are in transit and the engine light comes on the car will like too die at a complete stop. I put on foot on the brake pedal and give it gas so it doesn't die. Sometimes I would pull over and just turn off switch to stop engine and restart it. It seems flooded for 3 or 4 secs then it starts and runs fine with engine light is off. I already replace the MAP sensor. Also, I have lost power going up hills and kicks sometimes. My question is what does the community think the problem could be and resolve it?

What year/model?



Get codes for the check engine light read (when it is on) at an auto
parts store -- this will help quite a bit in diagnosing the problem.



Based on your limited description and the fact that the light keeps going on and off:

Probable EGR issue--accel and decel usually bring out bad EGR

behavior along with the inability to restart the car right away.
