Verified ignition timing & timing belt. Not sure if I mentioned this but I R/R fuel trim valve & the lean code is also gone now. Adjusted the accelerator cable to throttle pot ratio. Pot wasn t activating until 45 %. Truck isn t as doggy. Its making better power.
Still locks up. Had to take it to a Yale Dealer yesterday. I think its a software up date issue. Tech said it had the original software 5.1???
