1989 Questions for all other cars V8 Two Wheel Drive Automatic 36,000 miles

1989 motorhome, dolphin, chevy 458, automatic transmission--i have an intermittant problem. Usually when the engine is warm. Usually when I press the gas pedal to the floor for passing gear. Sometimes it feels like gas flow has stopped. The engine feels as though it is going to die. It will surge a little, then no response from the gas pedal.I have changed: fuel filter, carb filter, new fuel pump, new spark plugs and wires, new distributer, new air filter. It did pass smog test today. Just feels like an on/off switch to the fuel delivery system. Any suggestions would be greatly appreciated

Hi dunespit,

You mentioned carb so the problem could be due to a bad carb accelerating pump or power jet.

Have you tried servicing the carb?
