94 f150 5.0L. Starts fine, runs fine until reaching operating temp. Then, idle drops or engine stumbles followed by immediate stall. Can be restarted a few time for progress. Then, can only be started. Engine will stumble and stall as soon as you apply gear or accel. Cools down, runs fine again until oper. Temp reached. Then symptoms repeat. Already replaced, Ign Coil, plugs, wires, throttle position sensor (had a code for that). Tested clogged Cat by removing O2 sensor and running. No change. HELP. Codes are clear 111. I do have a habitual excess slip in torque conv code that has been there for years.
