The jeep starts and runs fine. Between 40-45 it starts to sputter and stall. It comes out of it around 50-55. It will do it again starting from a stop and going back up from the gears. It has no engine light, but the scan tool shows :

P0202 fuel injector 2 circuit open

P0171 system too lean bank 1

I cant find any broken wires on the #2 injector. I tested all injectors on an OHM meter and they checked 11.6- 11.5-11.5-11.7

I checked the cap and rotor. Everything looks fine. The slot under the rotor is in tact.

Any ideas on what I can try to check next or what the problem may be?

Thank you
 
Ever fix this issue? Same thing going on with mine.

No. It is kind of a toy so I have not messed with it much lately. I was hoping to get some advice on here, but didn't find get any. I still could not find any broken wires or connector on #2. I'm not sure if it is possible or not, but I am wondering if the injector is working fine at idle, but possibly not at speed or after warming up.

It is my son's jeep and the weather will be getting better in the next few weeks. He thinks he wants to try a new set of injectors and see if that fixes the issue. May be a couple weeks before I get time to get to it. I will let you know the results. Good luck with yours.
 
Not sure how much effort it is, but I would swap injectors between cylinders to see if it the issue changes cylinders before I throw parts at it. After that just ohm the wire back to the PCM while moving the harness around a bit. As well as verify the ground wire.
