any ideas, rough idle over fueling

[Rich320I]

Chaps, really appreciate some pointers with this, problems goes as follows car starts and runs fine, but it smells like its really over fuelling on idle. And the idle is very low and lumpy its idling around 600rpm and sounds quite rough, it revs up fine but the throttle response seems abit jerky. When the revs drop down when coming to a stop it almost stalls then sort of ”˜pulses’ up to about 900rmp then drops down to about 600rpm. If anyones got any pointers it would be really helpful. Thanks in advance.

Same as ever. Recon. injectors and eliminate ALL inlet side air leaks as the starting point.

cheers brian, to be honest i thought i had eliminated all the air leaks, i replaced the rubber boot to the afm icv which cured the last issue, and now this has cropped up, so im guessing it could be an injector problem then or is it worth checking the tps etc?

cheers for your help
