Engine Performance problem
1966 Mercury Comet V8 Two Wheel Drive Automatic 67,070 miles
just had shop put in rebuilt C4 tranny. Idle spd was too high, and tranny shifted hard. When I drive it short distances I have no problems. Its when I drive more than 4miles, or on freeway that stalling begins. My car stumbles and acts like its not getting enough fuel. If I try pumping gas pedal, it cuts out. Stalls motor. If I let off gas pedal it stays running at slower and slower rate, until attempts to maintain speed cause it to stall. What I have tried so far has failed to stop this behavior. This is what I have done so far. 1)adjusted choke cold idle spd down, adjusted both air/fuel screws one full turn out past " bog" point. So now car idles nornally, and shifts smoother also. 2)replaced air & fuel filters, added gas treatment. 3)checked fluid levels. Stalling behavior pursists.
