[jonnysamol]

Right well ive just changed my idle control valve but now when i start the car it will rev to 5000 and then stay there.
So is there something i need to do?

How do i reset the ECU?

Disconnect battery for an hour.

When you change a sensor it's best to reset the ECU to learn itself again with a new sensor :y:

For a hour? Is there no other way to reset it?

diognostics at a garage £40 will reset it.

Or apparently discconnect battery over night. Though im not sure on that one.

Well ill try leaving it for a hour, A man down the road works for the AA so he will reset it later when he comes to look at the car.

Thing is though hes not coming till later and i cant drive it with it revving like that dont evan want it to be runnning!

It says on the instructions i might need to drive at a certain speed for it to realise where the correct something is?
Any ideas on that one or is ressetting the ecu the best idea?

I leave it disconnected over-night just to make sure.. But a lot of people will say an hour.. some even 30 mins?!

Re-setting will sort you out mate don't worry.

different ECUs off different cars work differently.

heard different ways such as.

turn the key on n off the ignition 9 times

drive the car 9miles ish or 5 minutes

Battery seems to work but I also did it with...

Ignition On, Wait 30s, Ignition Off, Ignition On, Wait 30s, Ignition Off, Ignition On, Wait 30s, Ignition Off, Ignition On, Enter Immobiliser Code - Start!
