Have you tired O’Reilly. They will hook it up for free and run the codes. So at least you will know what it is. Or maybe you’ve already done yet

I have a friend who hooked me up a couple of years ago with some Cuban guys in KCMO. Kind of downlow but cheap. Don’t know if they do Jeeps but I just texted my friend to ask,

random misfire from your evap... try your gas cap

DallasRain · 07-21-2022, 09:23 PM

got new cas cap
i had an awesome sweet guy today check codes and nothing particular came up

so still troubleshooting

It runs great on the freeway but when I get to where I am going and park it for short while,then when I go somewhere after that it starts cutting out and chugging.

I think I need to get a horse & buggy lol

thanks everyone for your help!

Just leave it running when doing great , will not use much fuel @idle or trade in for a hybrid vehicle

I had that problem once, and it had to do with the changes that are made to gasoline additives when the seasons change. I think it was a computer malfunction that wasn't adjusting for the changes.

thanks yall

I was just told it MIGHT be a purge valve issue

Code P0440 can just be a bad gas cap. Usually start there.

0300 is cylinder misfire. Start with spark plugs and coils.

All pretty easy stuff.

There is a vent valve/canister by the gas tank that can get filled with junk and cease to operate. Purge valve is part of the system and is under the hood.

My car has had an evap issue for over a year, not a serious issue to worry about.
