ok, i did alot of work to my truck that i havent driven in a month and a half. pacesetter lts, ory, 4l80e, and a re-tune from nelson performance for all of that and delete rear O2 sensors, and EGR. i charged up the battery so it had a good amount of juice to it since it was dead. the truck turns over fine and starts but it will jump to 500-1500rpm then it will just die. i tried tapping the gas lightly and still it wouldnt idle. i just dont know where to start.
