okay i went up to my uncles last night and worked on my jeep(he is the best diagnostic person i know besides a machine) and i think we might have figured out a beter part of my problems. the #6 cylinder isnt firing, so we pulled the plug and switched it with one from another cylinder, that wasnt it, so we pulled the plug and checked for spark, yep we have spark, so then we pulled the injector and put a new one in it, that wasnt it, so we checked the power and ground to the injector, and it was good, so we check compression, and it had 120#. so not sure just what that problem is, but it has been running very rich because the plugs were all black and its puffing just a tiny tiny bit of black smoke. so we check the o2 sensor by unpluging it while it was running, and it made NO DIFFERNCE whatsoever. so could the #6 hole be missing because its giving it way to much fuel and retarding the timing(or advancing cant remeber which is which) to a point where just the #6 is missing? i didnt even know it would run without the o2 sensor working. has anyone had a problem like this before?
