High Revs on warm engine??

rabid spaniel · Jun 26, 2013

Hi, (This was in the Engine section, but had no answers!)

Recently noticed that when the engine (1989 19J) is warm (been driven for a while) when I take foot off the accelerator the revs stay high for a few seconds before dropping off. It seems to be the warmer the engine the longer it takes to idle down. On occasion the revs can even be high when restarting the engine if it is still hot. Radiator recently changed and made no difference - still happens.

Any ideas???

Thanks

I had a similar problem albeit related to the time that the pedal spent on in position rather than the temp of the engine. Check your throttle cable for kinks, remove the engine end of the cable and oil the inner as someone pumps the pedal. Also lubricate the moving parts in the footwell.

If it's not that then check the turbo inlet for lots of oil - that could be a more terminal problem though.

I will do both and let you know, thanks

Checked turbo - oil present, but not 'lots' relative to the oil everywhere else! Difficult to know what amount spells danger.

I will check throttle tomorrow AM and apply some oil.

Well - it isn't the throttle cable. OPebed her up when it was over revving and the cable was fully extended.

thoughts?

Fear it may be running on it's own oil

Not sure how best to prove or eliminate, but someone will know

Any excessive exhaust smoking when this is happening?

Sounds like the governor is sticking. Had this issue with mine, a strip down and clean out solved it.

Not that I have noticed. I have checked in the turbo and there is a bit of oil in there (but considering how much there is in the air filter I'm not that surprised!), but not a lot. I await some expertise........

Thanks - that sounds a likely one. How difficult is the strip and cloean (without access to my Haynes, I'm not even sure where the governor is!!)
