Truck runs smooth, quiet and lots of power, however when pulling a hill for a few minutes the engine starts to miss, once I get to the top and then start down the hill or come to a stop at a light, with in a few seconds it clears up and back to smooth running. I have done a full tune up. I can run it down the freeway 80 MPH zero issues, I have read a lot about this issue on 1990's GM Trucks, some point to the torque converter shuddering causing the engine ECM module to try and compensate for it. Has anyone experienced this? I think my next test would be to disable the TCC to keep the torque converter from locking and see if the problem goes a way. Any ideas or suggestions?
