Voltage is good Bob. I removed the Throttle Position Sensor and cleaned the contacts, dielectric greased them and took the rig for a ride. No luck, it shifts a little weird in the lower gears and will not go into gear if you put it into neutral. You still have to shut engine down and restart to get it into drive. I've been on the Williams Controls site and I believe I've found the right TPS if that proves to be the problem. I'll be taking the sensor into DD Monday for a check.
