Code 43. Causes Sluggish Performance, part of my overheating diagnosis, because the Knock Sensor is in the Coolant at the engine block. I wanted to verify all systems. thought I would share.

THX FOR THE VID. (4+3 Car is my 1985) I had a code for knock sensor (Needed replacement) and it cleared the code/fixed the issue.. My issue was, when I tried going WOT, the car would act as if it hit the rev limiter. On rare occasion, when I try going WOT, sometimes it will act the same way. VERY RARE however. NO CODES. I was thinking of doing this test, perhaps this is my issue? Thanks.
