05 silverado 4.3 v6 had a misfire so i put plugs wires cap and rotor on it and it is still missing but it pops really lound when it does miss??????????????????????????????????????
can you narrow it down to what cylinder is missfiring if so or if it is only one cylinder that rules out timing if it is one cylinder check the compression if it is ok 9 out of 10 times it is the injector
the injector sercut is messed up i guess thats what the autozone computer says its cylinder 5 that is missing
