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.

Hi Craig,

I had a problem with the sensitivity on my 92LT1. Ended up using a straight
+ 45 degree M/F 1/4 pipe fittings to move away from the block. Now it works
great. The teflon tape and less torque deal did 0 for me. Just remember
before you do any of this make sure you have no audible detonation and the
plugs show no signs of detonation.

Seems I read somewhere you can 'adjust' the sensitivity of the knock sensor
by using teflon tape on the threads, or screwing it in tighter or looser....
can someone verify this and explain how this works? This is for an '85
L98.....
Thanks!
