Fixing p0300 on Chevy Silverado 5.3

Fixed my 2001 Chevrolet Silverado 5.3l 4x4 random misfire and I want to show my process.
I was going to do a whole video of how to replace and diagnose spark plugs, injector and lifters, but they’re already a bunch of good ones on CZcams.

Thanks for video, my 04 has not had this happen yet but I need change plugs and wires soon

Glad it helped

The first thing i wound do is idle it in the driveway, pull off the spark plug wires one at a time, from coil, drivers side. Check for spark by jumping spark from plug wire to coil pack. If it has no spark, its a bad ground to wiring harness.

Great advice.

你好小兄弟! You should have shown how you take off cover to see the lifters? I am having similar problem. My cylinder 6 is still misfiring after I replaced all spark plugs & evap canister. I’m afraid it might something more serious like a broken cam shaft. Anyways good video
