[928uk] Throttle switch problem?

[Richard Armstrong]

John
Checking the throttle switch is easy. With the engine off get someone to 
depress the throttle slightly, with your head above the back of the 
engine you should hear the microswitch click just as the pedal moves 
from its rest position (it's and idle switch)

Even if it clicks it may still be faulty, but the actual contact can be 
checked with a meter by taking off the LH plug in the footwell and 
checking between terminals 2 and 5.

My car initially would not idle evenly and cut out occasionally, which 
eventually turned out to be a slightly dodgy contact between the engine 
water temp sensor and the plug - the sender has two outputs and feeds 
both computers. A variable signal between them confuses the system. 
Would not hurt to just pull off the connector and replace it (self 
cleaning wiper!) just to be sure, from memory it is the brown one on the 
right front of the engine
