RE: Temp Sensor Short

Here's the resulting problem.  When I turn the key to the
accessory position, my engine temperature gauge goes straight
to the top of the dial and the engine temp. idiot light starts
flashing.  This continues when I start the car and will not come
back down.

Richard, the shorting sensor is located on the left side of the block 
(sitting in the car) on the lower side of where the radiator hose goes into 
the block.  One sensor above, one sensor below a T that also houses the 
thermostat.  Water has collected in the rubber (worthless) boot and is 
causing your problem.  Also check the connection at the coolant overflow tank 
sensor for the flashing light. 

The car does start and idle poorly, but it did that before I washed the
engine.  

Vacuum leaks gave me these symptoms last summer.  Check crankcase breather 
line (below distributor, lower part of block) and big black boot from fuel 
dist. to throttle body, especially the bottom.

Hope this helps,
