So, I had some issues at Cordova about a month ago, car was fueling poorly, but still had a PB. On the way home the car sputtered and cut out a few times. The next time I drove to work, and the car died several times. Traced it down to the Maf connector, spliced the wires to band aid it, and fixed it. Picked up some new GM connectors from Justin, but didn't replace. So lately, throttle response hasn't been so hot, last time at the track was down 2 mph, with no KR on a smaller pulley; chalked it up to poor weather.
Fast forward to today...Car started sputtering on the way to work again. I barely got it home, figured my splice gave up, so I started putting on the connector I got from Justin.
Well, I clipped the wires, then stripped back the wires on the harness side..and they were corroded under the sheathing. In fact, I had to cut back the wires 6 inches to find good wire!
I just took it out for a drive, and holy crap! Major throttle response! Engine has never pulled so hard, or idled so smooth. Thought I'd share this just in case the corrosion under the wires is fairly common. Weird thing is, I set a code for TPS, not the maf. After fixing the maf wires, I tapped the car and found no issues what so ever with the TPS, I suspect that the wiring is somehow connected between the TPS and the Maf that if one is bad it affects the other.
