Hey Wrangler Forum,
I'm here to ask for help figuring out my Cylinder one misfire (P0301) code that intermittently comes on in my 1999 Sahara. I bought the jeep about a year and a half ago and it would come on, then disappear every now and again, nothing too serious, but not its's showing up every time I start my engine after sitting for more than 6 hours.
Replaced, checked and double checked my spark plugs. they look fine to me.
Replaced checked and tested the OHM's from the plug wires.
Replaced distributor cap and rotor. **see picture of wear on inside, I think I was sold one a bit too small, but don't think this is the issue.**
Checked ignition coil. (it's still there and no cracks or visible wear.)
The engine doesn't have a rough idle, or loud knocking, or pinging, gas doesn't smell funky.
The thing that stumps me is that it only shows up within 1 minute after starting, and if I reset the CEL after its warmed up, the CEL won't show up until it sits and gets cold again.
I'm stumped. I've thought I've fixed it only for it to show up the next day. It's been a roller coaster and a wild goose chase.
