I have a 87 GMC plow truck. This thing wont run at mid throttle. It idles fine, and will run wide open, but nothing in between. Real hard to plow snow that way. It has a throttle body for fuel injection. It will pop back through the TB at mid range, and if you hold it there it will stall. Let up rael quick and it will idle, or pop it to the floor and it will rev way up. Here is what I have done chasing it so far. Changed the chip in the computer, installed new plugs, new cap, rotor, and module, new throttle position sensor, new idle air control, and retimed it. I haven't changed the fuel filter yet, as it is rusted so bad it I will have to cut out a section of fuel line, and replace it with hose. It was changed about 6000 miles ago when I had the heads redone. I also haven't changed the EGR valve. Any ideas on this pain in back side? Thanks, Jack
