On the hunt and peck side of things, I had a flakey knock sensor throwing bursts of knock counts causing problems once. Found it by the data stream though. On mine, the port in block was also gunked up so knock sensor wasn’t in the water jacket.
what problems you were having from the bad knock sensor?

I’ve chased so many drivability problems over the years on this (93 5.7 TBI I bought new) I can’t remember specific problem (thinking it was intermittent stumble from a stop but not sure). I do remember going to datalog trying to find something which correlated with the problem and finding bursts of knock counts. Normally there would be a few counts kinda randomly occurring and every once in a while there would be a huge burst. Easy to change and not too expensive so I did and burst went away.
