Hi

I have a 1994 440 1.8 (single point injection). Just recently it has started
hesitating when accelerating. It seems to occur when the engine is under
load (ie, accelerating in 3rd from 30mph). Accelerating up through the gears
does not seem to be a problem.

The best way I can describe it is that the car gives a 'hiccup' (maybe once,
maybe more), but once the revs have climbed a little all seems well.

Any ideas where I should start looking?
