Ok, the gas cap is tight, and I replaced the HO2 sensor. The transmission fluid is okay as well. I did have the transfer case fluid changed. The grease in the rear end is okay too. Driving wise......it seems somewhat better and smoother, but it still isn't right. Upon the initial accelleration, I can feel the rear end not catching right....it does this as well every now and then when the gears change. Torque converter? Also, when I came to a stop, the engine sputtered a little like it was going to die...but didnt. The codes say that the voltage is still too low. I checked the wiring plugs/harness at the VCM and they looked fine, not gunky.
Hmmmm?
