Waiting on parts to come in. Replacing both camshaft position sensors with ac Delco brand. The two currently installed was some cheap crap. Will keep posted

Installed new sensor. Ran great until hooked coolant temp sensor up then 2 codes. Misfire on cylinder 5 and coolant temp sensor detected. The coolant sensor isn’t a doorman it is NTK
