    As above - any suggestions /experiences of this? Engine revs drop after 1-2 seconds at 3000 revs when stationary but drives fine on the road - when the revs have dropped back to ~2200 the build up again but engine won't hold at 3000

    All advice appreciated

    Crankshaft sensor?

    Don't know really - faults P0133 & P0134 were showing up but didn't mention crankshaft sensor

    The problem with the revs dropping is still there after these faults were cleared

    Engine burns plenty oil - would this be a factor?

    Had this before.

    TPS, just got a new sensor. I think solved it.

    It's called 'hunting' and it must be a common fault.

    What did you mean by TPS? What type of sensor can you recall?

    Spoke with a neighbour recently who had the exact same problem with a Corolla, it was the throttle body in carb, 3 different types fitted apparently
