Hey guys so this is my last resort I don’t know what else to do.

i have a 1995 Chevy Silverado 2500 4x4 with the tbi 350 small block 5.7l the truck will currently hold an high idle before it warms up then it goes to a rough idle and eventually will stall the original problem was I went to park the truck after doing some body work and I turned to back into a spot and the truck stalled I started it back up no problems then while investigating that problem I filled the power steering fluid up and it stopped stalling when the wheel was at full crank took it for a test drive around the block was fine until I switched from drive to reverse and the truck was idling rough and then stalled started it back up fine backed it up put it once Park and it started idling rough again. Since then I’ve been looking up everything about it and have replaced the EGR solenoid, EGR valve, IAC valve, TPS (throttle position sensor), the MAP sensor (manifold absolute pressure sensor), the coolant temp sensor ,and the fuel filter. i have watched the spray out of the injectors so I don’t believe it is the fuel pump spray looks even. I don’t know what else it could be but I would really appreciate any help anyone can offer.
