Engine Dies

[Gavin]

On start-up car idles correctly at first, but then drops from 900 to 700 then raises to 1100 etc. If I'm in a low gear say 3rd, and at about 2000 rpm and I accelerate lightly the engine is smooth and accelerates normally. If I however accelerate more rapidly the engine badly misses to the point where it almost stops. At this point if I dip the clutch, stop accelerating the engine returns to idle with no problems.

If I try the same again, but starting at around 3500/4000 rpm the car accelerates correctly both ways, (lightly and more rapidly) and does not miss fire. I don't think it's a fuel starvation problem as it works OK at higher rpm.

Any ideas???

Silly question but what car/year is it ?

Doh !! Nearly asked if manual or automatic, would have been a funny auto with a clutch !!!
