So, I have a new problem that decided to rear it's ugly head last night/this morning...
I first noticed it last night. I had just back out of the driveway to turn my truck around and back in the driveway. When I switched from reverse to drive, the check engine light came on and the gas pedal did nothing, like the sensor had called it quits. About 3 to 4 seconds later, the CEL went out and the pedal was functioning fine again.
This morning, I went for a drive, and for the first few miles everything was fine. I stopped at a stop sign, and when I went to go, I hit the gas, and nothing. I let up and hit it again, and it took off like normal. So then, I turned around about a mile down the road. After backing up and putting it back in Drive (had to make a 3-point turn), again, the gas pedal did nothing. I hit the pedal again, and just like at the stop sign, it went. I got up to like 10 mph and let off, because the stop sign was only about 20 feet away. Now this is when the tranny started acting up. It shifted really hard into 2nd while coasting towards the stop sign. I took off from the stop sign, and at about 12mph it shortshifted into 2nd (I think the TC locked up at this point), so it was lugging pretty good. Immediately after that, it downshifted like it was back in first (I was going about 18 at that point), but then immediately shifted back into 2nd, with the TC locking again. About 2 seconds later, it shorted shifted into 3rd, at about 22 mph. It still went into OD at the right time for the amount of throttle I was giving it (~40 mph).
Along with the erratic shifting, all of the shifts were really hard. And now, it does this everytime I take off from a light/stop sign.
Any suggestions to what this might be? Failing gas pedal sensor?
. I just finished the D60 swap last night and was all excited, but now I got this
Also, I just took it to have it scanned for codes, thinking that since the CEL had illuminated a few times, maybe there was some codes in there somehwere. Fortunately and unfortunately, there wasn't. But what I thought was really strange, is that when the scanner was hooked up, when the guy pressed enter, my truck started loping hardcore for a few seconds, barely running. He tried scanning it again after that, and this time when he pressed enter on the scanner, the truck loped hardcore again, and this time it died. It fired right back up though. Any insight as to what this might be all about?
EDIT: I suppose I should have posted this in the problem forum. Mods feel free to move this thread if need be.
