The dual-tank 5.0 extended-cab engine turns...no fire. Then outta nowhere, after I pressed the gas(unnecessaryly)over and over again, I heard fire popping so I froze. Next try I left the gas and turned the key. Fools gold because when it started I hit the brakes to gear-up and it slowed down so I caught the pedal. After letting off to test the work it under-idled, but the throttle didn't bring it back. I've changed the pcv and the rotor. What's next? Distributor cap, plugs, tps switch. What? Please save many lives. God bless you!
