Question about 2004 Chevrolet Silverado
Buy a spark plug test light at the auto parts store costs 5 to 10 bucks put the plug tester on eash wire then startthe car up and watch the light if it hasa constan arc then it's fine move to the next plug wire and do this proceedure till you find one with an intermant spark if you find one follow that wire to that coil pack and that would be the coil to replace. Note A bad valve or sticking valve can casue this to also a bad fuel injector or rings and last but not least an intake leak on the cylinder. Please rate if this was helpful.
