Intermittent code 43
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?

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.
