Car has never been over heated since rebuild and I know it is not 
overfueled because I have an EGT installed and you really have to stomp 
on it to get the temps to 1000 degrees and it will drop down very 
quickly.  As many have suggested, I will install a light to the bus bar 
and see if it comes back on during normal running.  If that Happens, 
then it is an easy relay replacement to solve the problem.  I intend to 
pull the injectors on the two cylinders that showed "erosion" and have 
them retested for leakage also.  hayden
