My car has been idling a bit weird for a while now, and is really jerky when you take your foot off the accelerator, and then delayed when u put it back on to the pedal.

I've replaced the throttle body, but nothing has changed. I was wondering if it could be a Lambda sensor failure? Or possibly lack of back pressure in the exhaust, because I have a Longlife custom jobby?

Car is a 6n 1.6 8v AEE

Any help is brilliant.

Thanks

I've done this already mate, made no difference for me. Good thread though, lots of people suffer it.

How did you go about resetting your ecu?
