My 89 Ram 318 fuelie auto, acted up around Christmas, where it will not accelerate. It starts and idles fine, but if you try to rev it up will not accept throttle, bogs, sometimes back fires. I replaced the fuel filter, and it has half tank of fuel. I started it this morn after sitting since New Years and it started with out a hitch, but will not rev up. Is it a throttle body/electical or what. Spring is here and I need a truck, any Ideas?
