Gentlefolk,
Since the car has been idle for a few months (and after trying an "Italian Tune-up")
I have a problem I believe may be down to my throttle switch - Idle is high (around 1400rpm) - squeeze the tube or disconnect the idle stabilisation valve, and the revs drop, So I believe the ISV is working. As I also had a problem with the heater, I thought vacuum leak, but get very measurable vacuum, and the heater problem was fixed by changing the heater fuse which had blown.
Disconnect the Throttle switch, and the revs drop back to normal (around 950rpm) so I suspect that is the culprit. My first question: Should I be able to hear it click when it is in the idle position (as per a 944 S2), second question - is it adjustable at all - it doesn't appear to have the adjustment slots of the 944 S2 one, so my guess is not. Third question - there appear to be cheap, aftermarket ones available, does anyone have any experience of their reliability?
Many thanks,
Tref.
