idle problem what parts should I change?

recently ive got an idle problem the idle was higher when the engine was hot than when it was cold- 1100rpm when cold- 1300rpm when hot

took off the icv cleaned it up twisted it to its furthest position and put it back together and reset the ecu. (the icv wasnt sticky it was twisting fine and is perfectly clean now)

started the car up really low and lumpy idle then when it got upto temperature the idle was perfect- 800rpm

Then started it up this morning really low idle 400rpm and was struggling not to stall then I came to a junction and it stalled- when the engine got upto temperature it was now idling just above 1000rpm and not 800rpm like yesterday.

I would of thought that since taking the icv off and apart as it has changed what the idle is doing then the icv is the problem and I should replace it but it wasnt sticky and it looked fine after I cleaned it and put it back on.... before I try and find a new icv I wanted to know if there was any other parts that could cause this problem

thanks

Clean the bore of the throttle body and the butterfly edges thoroughly, see what happens then. Use petrol or brake cleaner if immersing, cellulose thinners if used carefully and NOT immersing.

ok cheers chris I guess I will need to remove the throttle body from the engine to be able to clean the throttle body and butterfly edges?

Mine does this too, did you get any resolution to this?

turned out to be a faulty tps sensor

Thanks mate, will check this
