Cold idle issue

Ok guys obviously when car is cold idle is higher but mines is sometimes idling at 2k when cold, when you change gear at lower revs it will jump up to that 2k between gear changes, car is sometimes fine though.

 

Also occasionally when warm the car will idle at around 1.1 - 1.5k, this doesn't happen much but both probs are kinda annoying.

 

What can i check and what are the possible causes?

 

Cheers.

    This can be caused by the TPS not being in the correct range - if you search for tps and adjustment you will find a write up explaining what to do.

    Remove and clean your temp senders as they get scaled up

    If cleaning the temp sender - its the one on the left as you look at the engine bay. Clean the connectors up as they can get green and corroded.
