2007 silverado, check engine light works intermit, also miss fires intermit


Does the CEL "work" intermittently, or it comes on intermittently? If it comes on intermittently, that's telling you that the PCM has identified an issue and there will be a stored diagnostic code that should point you in the correct directly to begin troubleshooting. For example, if there is a stored code of P0304, that means the PCM has determined based on sensors that cylinder #4 has a misfire. You will then need to determine if that misfire is due to a spark plug issue, a coil issue, a coil/plug wire issue, fuel injector issue, compression issue, or vacuum leak.

Engine Code 301


Code # 301??? That is NOT a valid Diagnostic Test Code (DTC) for the engine control system on a 2000 Mercury Sable.

Assuming that you mean P0301, that is a cylinder misfire code that is identifying number 3 cylinder as the cylinder with the misfire problem. MANY things can cause a cylinder to misfire including spark plugs, spark plug wires or boots, burnt valves, broken valve springs, blow head gaskets, cracked cylinder heads, bad or dirty injectors, faulty injector control circuits, Failed ignition coils...the list goes on....proper diagnosis required.
