:confused:

For the past week I have been experiencing a fast idle up to 1.5k instead of the usual 750/800, which is most anoying in an auto ( NA by the way).

Checked Yellow connector to rad. Cleaned it and all ok (Elec fan does not come on unless v.hot).

anybody got any thoughts!? :bow: Please.

TPS position, stuck idle control air valve, throttle position closed switch not making, air leak are probably most likely

Yeh i agree it will either be a vacuum leak but that usually causes a more loopy idle.

The TPS is easiest checked with a Multi Meter, but that would also give you a hard start.

The 'auto coke' air bypass valve could be stuck open giving you a cold idle constantly.

Or the water temp sensor is faulty.

 

I'm not up to scratch on these engines so i couldnt tell you where these parts are located.

All ok now for the moment!!, thanks guys.
