Engine codes

[tkocurek64]

Does anybody know the remedy for engine code 300 on a silverado 2500 with the 6.0???

The scanner said i had a random missfire

Check plugs, coil pack, injector and compression. The code should also be telling you which cylinder. Last time I had the code it was a burnt intake valve and wasn't a simple fix.

The code translated to a random misfire meaning more than one cylinder

Last time the plugs and wires were changed?

They look original but I just changed them. And it didn't seem to help

Can you perform a crankshaft re-learn?
