I have a 325 sport, and under very slight throttle it will judder, as if the AFR is wrong, or its not firing on all cyinders.

Its fine on full power, and sometimes fine on slight power; say upto 5% throttle.

Othertimes it will be stuttering and kangerooing, on low power, if i floor it or just put more throttle it will be normal.


Any suggestions on what to check, or common problems?

Have a look at the TPS, see my thread below, is the video anything like your car.

I tinkered with the TPS, cars tranformed, mind it could be something else :mad:

I had a similar problem, with a judder but at any sort of throttle, turned out to be an Injector
