Ok, problem is getting worse, MUCH WORSE! The exhaust system, and the fire, was just coincidence, I guess. Now the jeep runs like total crap below 2000 RPM's. Doesn't run good at all. 5th gear is almost worthless, as it has no power. It just continues to slow down. 4th doesn't do great either. I got a stethoscope and checked all the injectors, and they all sound the same. Going to check impedance after I eat something. Can't find a vaccum leak. Also going to THOROUGHLY check all the plugs, wires, cap, and rotor.
When doing a continuity check on injectors and wires, what should i be looking for? On plug wires, I assume very low resistance. On injectors? I'm REALLY close to taking this thing to the dealership, and giving it the 'ol boot. Right now I'm not sure I'll make it to work each morning.
