[QUOTE="Kman11, post: 15884603, member: 179746"] Hey thanks for taking a look. Swapping the 02 sensors - That would mean the KR is happening because of what the 02 sensors are telling the ecu? I always thought the knock sensors ONLY responded to a "noise or vibration". Fuel injectors - They were bought and installed brand new as of last year. Yes there could be a low flowing one. But would that explain why the KR only reads when throttle is stabbed? If i ease into the throttle all is well.. Happy to try this is we think it's a worth while time investment? Plugs - I installed a brand new set, no change. Interference - Interesting thought. No clue how i could isolate this. Log Spark Advance - Not sure how to do this. I have the lund ngauge and use there log option. Anyone know if i can add that on? -------------------------------- At this point i'm really certain it's NOT SOMETHING RUBBING / TAPPING. As i have 1 thousand zip ties holding every damn thing that could make any sound in place. I've screwed with the exhaust more times then i can count. I've disconnected the belts, blower, etc. We are going to put the scan tool on it tonight again. Before we just revved it to see which knock sensor was showing knock. Tonight we plan to take it out for some test hits to see what it's showing us. I'll let you all know what we find. [/QUOTE]
