Hey guys, I've been playing the the laser just trying to get a better understanding of what the ecu is doing at what point and why. Problem is she knocks and I can't get it to go away. Here's what's going on:

-Into the throttle anywhere from 1500-2700rpms results in 43counts of knock
-The O2 cycles as it should and my fuel trims are all 3 90-110
-Changing gears to raise the RPMs will make the problem go away
-A hard rev will make the problem go away for a minute or two
-At WOT I never see a knock count higher than 2

So what are your thoughts? I'm leaning toward fantom knock.

I would call nate the authority on this one... hopefully he chimes in. I agree that randomly replacing every part that could have an effect on something that may or may not be causing any sort of a problem is a huge waste, not only of money but also of time. Sometimes you've got to use the guess and check method when you're plain out of ideas, but I think it's much better to trouble shoot before hand.

Ask Nate and Kicks about 43 counts of knock... especially at WOT in 3rd gear... laugh.gif laugh.gif laugh.gif
