This is the thread that you referred to me about adjusting throttle cable:

Look in the end of this thread to see the WOT switch in aluminium.
If there interest contact me and we will work it out.

"After a couple of hours with the car, Paul reported back that the throttle microswitch was in fact broken and the throttle was not opening fully"

Very very basic Porsche info that all good UK Porsche mechanics know,
i.e. hardly any great revelation from here in the USA given the symptoms.
Furthermore, a search on Rennlist or a thread indicating the problem would
have pointed in the same direction. Furthermore, there're many UK Rennlist
sponsors, e.g. 9m (NineMeister), that are very knowledgeable about 964s
and have far more insights than some of the so-called tuners here in the USA.

The plastic cam actuator is only used on the later plastic inlet cars. Alloy inlet have a different throttle body and microswitch mechanism.

Huh? I didn't say it was a revelation, I don't get your point. Steve Wong had already suggested what the problem was. My mechanic was just investigating that was the case with mine and fixing it for me. The main reason for my post was to help others, which everyone else seemed to get... Thanks for your response anyway

Unless we have a difference of terminology, I'd have to disagree with the above statement. My car is a February 1990 build with the alloy inlet manifolds and had a plastic cam for actuating the WOT microswitch...are we speaking the same language?

Apologies, I was referring to the wrong switch!
