If I start up, drive down the road and lift off the throttle in say second gear, the car will jerk/kangaroo. To avoid this jerking I dip the clutch before lifting off the throttle. What happens then when I dip the clutch is the engine hunts and often stalls unless you rev it a bit.
If stationary and I blip the throttle, as the the engine revs rose, it sort of skips/jumps at approx 1800-2000rpm.
I had this exact issue on a 2000 W reg Rover 45 1.8 10 years ago, and in 6 years I NEVER got to the bottom of it!
I have changed the 02 sensor. No difference.

That sort of thing used to happen if the choke wasn't working and the mixture was too lean. How it works on the petrol engines though I don't know as I run a diesel.
