Problem with 454 in 1988 Dolphin motor home. Upon turning off ignition, an explosion often occurs in the exhaust system. Also, when pressing the gas pedal almost to the floor, during upgrade, the engine sounds like it is gasping for air and starts losing power. The plugs, plug wires,rotor, and cap, were recently replaced by a brake muffler shop. Further, often the ignition switch will not stop the engine, and it is necessary to pull out the headlight switch to make the engine stop. I know this sounds bizarre. Further, the engine sounds like it is diseling after turning off the ignition switch.
Suggestions please. |
