Hey guys...
Today I burrowed my schools $4000 scan tool to check things out just because. Everything looks perfect, except I get a knock signal if I hit a hill in third gear and start pushing it. I also get a signal when I am on the highwayand start givin' er' in fourth gear. Its a super quick signal, like it only shows up for a split millisecond every roughly 5 seconds in the described situations.
Other wise, at high rpm and WOT, the scanner shows no signal at all. So maybe its a false knock????
I run 91 octane and have been since the crate 3.4 motor went in 13,000 miles ago. It is run on a stock GM 2.8 TBI computer with a large Holley 400 cfm TBI unit the feeds the 3.4 PLENTY of gas. I also have cold heat range spark plugs (UR6).
Should I be worried about this reading??
