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.

Also, anytime you have 43 counts of knock I can guarentee its phantom knock.

Not true at all. Actual detonation will give you 43 counts of knock. And guess what a faulty coil will give you at lower RPMs? Detonation. Funny how all that works.

Don't act like an expert because you can quote vfaq. The steps listed can all cause knock to show up, but most aren't compliant with the rest of his symptoms. Trying to replace all those things will not only waste a lot of money, it also won't give you a true indicator of what was causing the knock.

And unless you want to donate the money and time, he should start small and easy. That's why many of the parts you suggested aren't where I would focus my attention, and that's why I think its a poor troubleshooting procedure. Anyone else care to chime in on this?
