Hello everyone I have a 1988 gmc k1500 with the 5.7 tbi I installed a new ac delco knock sensor and I got a code 43 after driving for 10 minutes. Could this be a defective sensor?
Backstory the truck is an original 5.0 tbi truck but I installed a chip from Harris performance to run it as a 350 I've installed 350 injectors, egr deleted, new coolant temp sensor new map sensor new tps sensor new esc module new iac sensor. I wanted to put the 350 knock sensor in but it keeps throwing codes. The old one does not any help is appreciated and thanks in advance.
