well then if thats the case my wires have been on my car for the last 127,700 miles lol.

 

The LT1 spark knock sensor also is more sensitive to other changes in the motor.

The LT4 sensor is not as sensitive.

 

Just a little clarification...

Both the LT1 and the LT4 use the same actual "sensor" that goes into the block, the difference is the "knock module" that sits with the PCM that decides what is spark knock and what is just enine noise.

 

I was close, Mind is a little fuzzy @ 1 in the morning.[sm=sleeping.gif]

Got a P/N for the knock module handy?

Thanks.
