light throttle stumble
I've noticed this is getting worse over the last few days.
If I drive at steady/light throttle is get this stumble, if I give more throttle is seems fine, as soon as I back off to a light throttle again it starts to stumble again. I havn't done any of the usual tune up stuff yet I was just wondering if anyone had any likely places to start. |

i had a similar prblem that evolved into the car not starting and running like crap. It would surge at light throttle and get better as i floored it. Turned out it was a bad mass air. You can check the mass air by tapping on the sensor with a wrench or something while the car is on, if its bad the cars idle will change. Dont know if its the problem or not, but its an easy test. just my 2 cents.
