Hi all
cars been playing up lately really need to get it sorted asap just cant figure it,
Starts fine and does how it should until it is warmed up once hot enough idle will rise briefly then drop to 0/500 revs .
if driven on a motorway pull off and stop at a junction its fine, keep stopping and starting it just runs like a shitter wanting to stall all the time.
driving on boost and normal driving is spot on just when ya coming to a stop theres a problem

any help would be great
thanks in advance
steve

Check the TPS is set correctly, the procedure can be found in the Awfully helpful Electrical section.

An easy way to check it before you do that is get it to the point where it does this, remove the TPS plug and see if it still does it. If it does, link out the bottom 2 wires of the plug with a bit of wire and if the idle returns to normal the TPS needs adjusted.
