Alright so in the tune knock sensitivity was set low, also have a LT4 KM. Yet I get a code 43 that pops up and goes away as I'm driving. What can I do about this? Its not knocking so far as I know, SES light didn't pop up during the dynotune either. Like I said it shows up then goes away for a few minutes, then comes back, sometimes doesn't show up at all. New AC Delco knock sensor also. I'm perplexed. What can cause it to trip?

Thanks for that, but it seems I need the facing page according to that, as my code is intermittent. Its driving me nuts, some trips it never comes on, other times it pops on and off multiple times.

Bad connection. Mine does it, too, and sometimes I have to get under there and re-arrange how I have it plugged in.

Might want to try a new pigtail. Cheap and easy cause to eliminate

Yep, it is often the connector. Heat is hard on it. A pigtail often fixes that.

I'm having the same troubles with my 383 right now. Tried a new sensor, module, rewired it and still no luck. We've tried getting the sensitivity down through tuning and still no luck. The worst part is when it happens im pulling 7 degrees of timing at idle and anywhere between 10-12 at WOT. I've checked plugs and they're fine so I'm at a loss. Any other ideas would be great.

Thanks guys, I'll try a new connector. Stuff freaks me out some trips it doesn't even pop at all. I suppose after 14-15 years the connector probably isn't that healthy being exposed to the heat as stated and sorta being in the open down there.
