Is it possible for an engine to knock and see no KR on a scanner?????? Under a WOT pull I can hear it knock plain as day. I cringe and let out of it........... But I see no KR?

Im bout to drive my truck into a wall......

Why does it do this **** on stock timing????????????????????????????

 

Wow. Good thing there is sooooo much help on this board.

 

prolly just got a tank of bad gas or a 1/2 a tank of the stuff....go get some octain booster and see if it kills your grimlin...

 

i got some 114oct that could prob help ya... or hurt? haha

 

did it help any....

 

I've seen the same thing on mine. You can hear the pinging, but nothing on the scanmaster, or HP Tuners. Then, other times, I see kr on the scanner, but don't hear anything.
