Is this a Dynaflow issue?
Sometimes when gaining speed, the engine briefly stops responding to gas pedal. Car starts coasting. Two seconds later car responds to pedal again. Motor is NOT stalling. I have the Variable pitch dynaflow on a '58 Special. 2 turbines. Wondering if it's a very slow transmission shift to 2nd gear? Transmission slipping? Transmission fluid level is fine. Dirty automatic trans filter, faulty converter pump? Vacum leak in the fuel vacum system? May be hesitation/faulty accelerator pump in carb?
