this morning i was driving and as i was driving, the check engine light flicked on, then off almost imediately... then at the same time a light right above the gas guage flicked as well, so fast i couldnt tell what it was... I had more then 1/2 a tank of gas at the time.
Anyway... about 2 hours later, i was accelerating to highway speed and the car bucked, and jerked before kicking into speed... the service engine light came on and stayed on.... until i shut the car off when i started it back up, the light was off....
the car had no problem reaching highway speed after that......
my questions are:
1) what is the light above the gas guage, i couldnt find it in the manual. I had more then 1/2 a tank of gas at the time.
2) any idea what the buck was?
