G'day all,

I seem to be having an issue with the idling in my car. When ever it comes down from 2krpm or higher, it drops to 500rpm before returning to it's normal idling speed. Occasionally, it fluctuates 2w00-300rpm downwards when idling as well. I recently had issues with the thermostat housing and I thermostat, which I recently replaced, however it still seems to be getting warmer than it is meant to. Not sure if that's related, but can anyone give me some reasons or possibilities as to why this is happening?

Muchly appreciated. Cheers.

Mines idling about the same as yours at the moment. Seems pretty slow off the mark too. As for getting hot, your radiator might be starting to get blocked? Seems to be the weak point in the system if it hasnt done a head

Righto, might check the radiator out. Does anyone else have any ideas about the idling thing?

engines not running lean or something is it?

check out the water pump too.

as for the idling, have u looed at the usual suspects like plugs and leads?

clean out the throttle body with a rag and a can of carby cleaner, its most likely all carboned up, once you've done that, disconnect the isc, set the base idle and you should be right.
