I'm Awesome
Not yet. Haven't had a chance when the truck was cold to actually start pulling plugs. I will check that this weekend though.
Finally got a chance to change my coil last night and some interesting things happened. First, the truck seems to be running better albeit far from what I would expect. Even in when the truck made it to Closed Loop, I still had enough power to almost spin the tires going around a corner. Truck does have locking diff though. Second, I got both the HRT and the O2S readings on my code reader to check out. Then the scanner popped a Pending DTC of P0131 which said low voltage in O2SB1S1. Checked the live data and saw .000. Confirming the original diagnosis. Still planning on swapping them out Friday after work. I don't want to get my hopes up that changing these stupid things are going to give me more power. I suppose thats all possible but I drove our shops 1997 C3500 flatbed towing the same tractor and trailer that i was towing when my truck stranded me. This truck has a Vortec 350 but easily did better than my 454 in its current state. Hoping that by the time we are said and done here, I'll run circles around the shop truck.
I hope that is the issue then, definitely keep us posted. It really shouldn't even be a comparison between the two. Unless the C3500 has numerically higher gears?
