Re: Knock Sensor Question

         How "safe" is it actually to do this?  I have a knock sensor 
problem with my 91 LB9...no audible knock and quality gasoline.  Can't 
solve the problem.  Replaced the prom, but still get intermittent codes...I 
wouldn''t mind a fix real soon since every time I hit the gas I get 20 deg 
retard right away.  Really slows the thing down quite a bit.
