How do you reset the ecu? My idle is sitting a bit high (1400). Would resetting the ecu (battery off?) fix it?

Immobiliser off (IIRC) electrics on, slowly push throttle pedal to the floor and release 5 or more times, electrics off. Leave off for a few seconds, leccky on, start, hey presto, ECU is reset.

I would check that the IACV isn't clogged up with sh*t too, they get pretty manky with soot. A quick blast with carb cleaner will sort.

Cheers Richard, I'll give it a try. You are a mine of useful information!

More of a pit of useless info that sometimes comes up with gold!

The IACV should be in charge of the idle speeds though and (IIRC) it is done by engine speed so should never be a problem, therefore check the IACV isn't clagged up while you are there!

I dont have a CLUE what or where a IACV - remember I'm the guy that takes my car on a 70 mile round trip to get a wiper blade fitted and back the following week to replace the battery!

But resetting the ECU as you suggested seems to have done the trick.
