hey Scotty love the vids OG. I have a 1998 Jeep Grand Cherokee Laredo with 3 error codes a p0455 evaporative emission system leak detected (gross leak/ no flow)
p0320 ignition/distrubutor engine speed input circuit
p0442 small leak I know it’s emissions like the p0455 but what is it usually?
Remove and reinstall the gas cap and drive it for a while and see if it goes away. These small evap system leaks are usually a worn out gas cap.
thanks I actually tried that one Nd did the evap purge valve my self so now I’m thinking it’s maybe from fuel tank or charcoal canister but what about the p0320 one because that’s one I’m a little confused on because my car starts up fine and drives fine can def be better but I don’t know if it’s my crankshaft position sensor causing code
