I have had a look through recent postings and I cant find anything similar, so wondered if someone could help me out with an idle problem on my Golf.
Basically I have two faults that are intermittent. They normally happen from cold, or if the car has been left for an hour or so.
Either the engine will just stall (ie you start up, drive off and then after a minute or so stop at lights with the clutch in and it just dies). Or, after driving off after a minute or so it holds really high revs and wont come down (eg anything from 2k up to 4k rpm).
Its a pig to start if it stalls, or if you switch off whilst its holding a high idle. Takes about 30 seconds of kranking.
I have tried spraying in carb cleaner in the throttle, and lubed up the throttle return spring but it doesnt seem to make any difference.
My thoughts are either a temp sensor or throttle position sensor, but I am after any help on how to track this one down.
