2002 Di 3ltr fast idle problem

[GQtdauto]

Our GU has just started to idle at 1500 rpm for some reason , have cleaned the maf sensor no change , checked the switch that you can increase the idle when cold and it does nothing at all probably because it's already over idling .
Anybody come across this issue before and how was it fixed ?

Check wireing and plugs to the ECU and also the TPS. Any codes?. Might be worth the old disconnect the battery for 10 mins and reset everything?

Bugger can't find the pin for the radio , turned the car inside out but it must have been turfed by the missus , so until I can find the code or a cheat for the code might give disconnecting the battery a miss , it's due for a service anyway .
What I did find made me laugh , the old service receipts from the dealer which includes clutch fluid and test clutch operation ,not bad for an auto .

Problem solved by using this strange idea from another site , just let it idle for 5-10 minutes ,mine took 4 minutes then clicked back down to normal revs , restarted and still good , don't know how or why this worked and don't care just happy it's fixed .

cant you use a 9v battery connection so you can keep memory

No need now TD , as for the radio pin will cross that bridge when I fall of it .

The only way I've fixed it is to pull on the accelerator cable at the top of the pedal and instanly drops back to normal. No mechanic has been able to stop it. I just put up with it.

It's the wife's car so no idea if she hit a pothole , I did try revving it but with all the electrics wasn't game to do too much so lucky I found the idle fix which is still working for now .
