My brother is having some issues with his XJ. I tried a search, but I got confused and never really found the answer. So I figured I'd post with his specific situation and hopefully someone will know where to start looking or know how to fix it.
His XJ is a 1996, 4.0L, AW4
The situation:
This past weekend, he changed his plugs, wires, cap, and rotor. The plugs that were in there were, i think, bosch and he said the gap was really wide and they appeard to have been in the motor for a long time.
Once he was done, the motor started to run really rough. It never really ran all that smooth before now, but it was much worse after the tune-up. The check engine light also came on with a "0202" code (P0202 (M) Injector #2 Control Circuit An open or shorted condition detected in control circuit for injector #2 or in the INJ 2 injector bank.)
He took it over to a friends for further testing. With the motor running, he pulled the fuel injector for the #2 cylinder, there was no change in how the motor ran. So he pulled the #4 injector and the motor bogged down. He reinstalled the #4 injector and repeated with the #1 injector with the same results.
They then tested the injector connector. It wasn't reading any ohms whereas the #4 and #1 injectors were reading around 12 ohms. The also tested a little further up the wire with a probe to try to eliminate the possibility of a bad connector but they got the same results.
Any help would be greatly appreciated.
Thanks
Steve
