Range rover 4.0 SE, R reg (120k miles) auto. New leads, oil, plugs and air filter fitted two months ago.



Started today, felt like it was missing on one cylinder, very erratic tickover jumping between 300 and 600 rpm, Also at low speed pulling back, put foot to the floor and every thing ok over 30 mph.



any help or suggestions appreciated

Vacuum leak? Any pipes fallen off under the bonnet?

Badger> Possibly a Lambda probe gone?

And my suggestion: crankshaft position sensor.

Check 'em all and you'll stand a good chance of finding the problem.
