Subject: Re: High RPM when hot

Mads, The cold start valve can be tested very easy, Unscrew it and 
lay it on a paper towell on a piece of cloth or something to absorb 
the little bit of gas coming out. If it continus to squirt after 
about eight seconds, then I would look into replacing the thermo time 
switch. Check all the wiring on the micro switch for the idle speed 
motor unit, make sure your connections are ok on the idle speed 
motor, and then you may want to look into the air flow meter 
adjustment. If all these things are ok to the best of your knowledge, 
the the idle speed thermister may be bad in the water pipe. I will 
put it on the web site tomorrow. Follow this

Interesting. I have a very similar Problem, only that it's more with
the lower gears and reverse.
Also after driving a while (especially in hot weather), I experience
increasing difficulties in shifting into the reverse, 1st and 2nd.
It gets that bad that the gear does not sync anymore in rev and 1st,
what ugly noise! It gets better if I then shift into neutral and
sort of "pump" with the clutch pedal a few times before trying again.
I had the transmission oil changed, but it didn't help... :-(
Perhaps it's something with the clutch ?

I also would be thankful for any ideas.
