when driving the engine revs between normal and 1 thousand revs more than it should, also when i stop at a junction it will idle at about 2 thousand revs for about 5 to 10 seconds befor retuning to its normal idling revs!!!!!!!
your problem is that your throttle position sensor is incorrect ,you can adjust them with a diagnostic tool ,normal reading state that they should be set at 0.7 volts but i set them lower if it a old sensor you need to remove and drill out the mounting brackets to adjust beoned the setting .
the sensor will cost around £70 new and will cure you fault.
