My friends 1997 318i coupe seems to be suffering badly on acceleration in first gear only. It hunts severely unless the clutch is slipped, it seems to step up the revs in 1000rpm steps as if you are jumping on and off the accelerator at those points.
Other gears power seems to be normal, but I'm not sure how powerful this should be.
It hasn't been all that well looked after, still has same spark plugs in from when he bought it, but he would change them if he thought it would help.
Feels more like an engine problem rather than clutch or drive related, just too severe and on/off.
Any clues?
