If your fuel pressure rises,from 42,pound for pound with boost your fuel delivery is good. You won't know this until you observe the gauge at WOT.Was able to install a fuel pressure gauge. Line off at idle - 42 psi. So It looks like the fuel system is pump is good.
IAC could be bad, but with it reading 00, I'd bet the engine is getting it's idle air from either a vac leak, or the throttle body is open too far.
What's the TPS reading at idle?
Earlier in this post you said you just installed the knock sensor with just a wrench. Did you ever remove it and torque to 14?
Sometimes I hear what I think is pinging but my scanmaster doesn't show any timing pulled. Is this possible? The knock sensor is new. Thanks.
Leave the stock pcv on and reset the ECM, drive it and see what it does, that RJC valve sent my BLM's haywire...No it was wrench tight. 14 ft/lbs is not that much, I don't know if that is the issue but possible.
As far as the vacuum leak situation goes, I just decided today to swap out my pcv valve from rjc to the stock one that was on it prior to the rjc. I did notice that the IAC number was in the upper 30's vs. the 00. BLM was the same value after the swap. I'm not sure if anyone will find anything from this... Still looking for any leaks that would spike the BLM value though. I might have to get a machine as mentioned to figure this out.
Yes- Scanmaster only shows the ECM response to knock signals. Brad
I am thinking it would take quite a bit of knock to be able to physically hear it? Is that a safe assumption? I had knock and only way I could tell was scanmaster.
I thought you mentioned you did not torque down the knock sensor? if so, I would remove it and start over with installation with torque.

Removal of the engine is not necessary when replacing the knock sensor. Just remove the coil module and bracket. I used a long extension(I think 10") to do this. I'm sure the 10" was over kill but i didnt want to make a trip back to the parts store. Good luckLike I said it was plenty tight when I installed it but you could be on the right track. Is it possible to reach the knock sensor with removal of the coil back and bracket? I really don't want to pull the engine to check the knock sensor...
