Hi guys,
I have a 2002 auto Mistubishi Challenger 3.0 v6 which has some issues.
About a week ago I ran out of petrol, I called roadside and had it filled back up.
About 4 days later, the engine light came on and the car starting missing (hot and cold) it also idles now at only 450rpm.
I initially thought the fuel must be the culprit. So I replaced the fuel filter and put a bottle of injector cleaner in it.
Still the same problem remains.
I decided to use the manual method of scanning the Ecu by bridging port 1 and 4 on the OBD2 connector to retrieve the codes.
I got a 2 codes, one was the EGR vale and the other was the ignition 3 and 6. (coilpack).
I removed the clip off that coilpack and the idle did not change. I did the same test on the other 2 banks and the idle instantly drops when u unplug them. So I decided to swap the coilpack over with a good one and test again.
This is where it gets weird....when unplugging 3 and 6 the idle doesnt change again, and yet it does when unplugging the others, even after swapping the coilpacks. Am I looking at an ECU or wiring problem here? Is it just a coincidence that this happened 4 days after running out of fuel? I'm at a loss at the moment and don't have the money to pay some mechanic to root around with it until he figures it out. I'm all for trying to do as much as I can myself before resorting to that.
also, I decided to blow out some of the fuel from the old fuel filter to see what it looked like. It was pretty brown and dirty...
Anyone with any ideas, I would be most appreciative!
Cheers,
Pete
