1996 305 vortex Cheyenne.
I'm getting a P0300 code. Solid SES light, after driving it flashed on a 300 mile trip. Flashed again 30 mins later and again a few minutes later. It's running smoothly. I'm doing spark plugs, wires, cap and rotor. But don't think it's it?
Recently had timing chain cover, oil pan gasket replaced. But SES light was on before then. Smells a little like burning oil. Other than that it starts and drives fine. Please help. Thank you.
