Checks out to be the #1 cylinder misfire BUT when I gas up, the light goes out —- Me and the mechanic are stumped by this — any ideas?
Does not seem like a misfire sooo-—
Sooooo.......
What's the symptoms????? Just the light?
You have too Help us help you.
So if the light illuminates and PO301 is the code in the ecu if you could go out and pull the plug wire from cylinder one, would it make a difference in the engine smoothness or not?Just the light —— and only comes on when it hits a 1/4 tank —— What else should I post-— I am lost

No running rough? Power loss? Hesitation? Surge?
P0301 is a misfire code, should run bad, at least for a moment.
I don't see a correlation between the 1/4 fuel level and code though, that's odd.
I would probably keep the fuel level above 1/4 for awhile just to make sure it wasn't a coincidence and see if code returns.
It is very odd... I traded for this jeep three weeks ago. Passed the Nevada Smog check, what a joke that is, just fine... Twice now, tank hits 1/4, light comes on. Fuel up, about 20 miles or so of driving light goes off. Back to a 1/4 tank light on-- repeat about 20 miles drive, turn off restart light is off ———
Just to note the crank position sensor is what helps identify a missfire IIRC. Was anything done with the crank position sensor recently?It is very odd... I traded for this jeep three weeks ago.

You have the wrong forum. This forum is for 97-06 TJs. You have a JK:Did this ever resolve? The EXACT same thing is happening with my ‘15 Wrangler!
