Hey, good catch! A problem I had recently on my 09 was a misfire, code for "open circuit injector number 2". I chased it for a while then gassed up and the problem went away, runs smooth as silk. I had put some bad gas (siphoned from my rarely used pickup) in and caused it to run rough. Can't explain why it said open circuit, or just number 2 injector. I thought I'd share my experience, and congratulate you on being a damn good mechanic. Thanks for your video!

I know this is an old video but I have seen a video of the anti freeze leaks from the temperature sensor and it will migrate up the wires and burn out the connector

I got the same problem but its p0202 for injector #2. took the connector off of injector #2 and found no corrosion or water damage so this harness must be the problem. thanks for the help.

Just got that code today . My last time it was a injector. Hopefully it’s something easy this time

I have a P0201 most of the time then the P0301 with a misfire shows up. I clear them with my scan tool and let it sit overnight and then it’s fine the next morning. Then it’ll come back a few days later. Replaced injectors, seals, PCM. Still occurs. Must be a harness issue like this video

Yes I have a 2002 harness with a bizarre red sideways clip that does nothing, no idea under the sun how to pull it apart. Ended up breaking the tab on top and its still welded fast. Why not just a simple snap plug on everything, why does each one have to be creative and unique, like a freaking Mensa puzzle? The designers of Jeep connectors and clips should be boiled in motor oil as I'm concerned lol

Yeah that red clip is a safety lock. It has to be slid sideways before you can undo the main connection. Yes it is overkill and dumb

I’m having a misfire on cylinder 5 and my injector circuit on injectors 1-6 are all open constant. I had water in my injectors along with corrosion in the harness but not to the point that the prongs were broke. I cleaned all of that checked compression checked all grounds and changed injector on cylinder 5 and also the vacuum is good. Still haven’t found my issue a week later. Any advice ?

Does the windshield wipers go through that harness. I have a intermediate problem with the wipers not working also along with the misfire codes. I’ve had it happen to 3 and 4 cylinder

I had some wiper issues also but it ended up being the multifuction lever which is basically the turn signal and wiper function lever on your steering column

insanely rough. I had a corroded injector connector as well as this. The little metal prongs on the injector corroded and broke off in the plug. That was a lucky catch as well.

This was not a plug issue. Also I think you either mean 3.6 like the newer Jeeps have or a 3.8 like this has. I'm using platinum plugs in my 3.8 for 3 years now and not a single issue.
