check engine light code "P0300" random miss fire
I have a 1998 Chevrolet Cheyenne V8 5.7 ltr. 2WD. My computer throws "P0300" random miss fire code. I just replaced spark plugs and wires, rotor and cap and timed it. swapped in a 1999 Suburban engine 2yrs ago. Anyone got any direction on the matter?
Is this a good question?
