What causes acceleration in a 97 Chevy Blazer? 97 chevy blazer 4.3 idles great but upon acceleration it starts to surge, changed just about everything, fuel pump,cap rotor, wires, plugs distributor injectors, crankshaft, cam, throttle pos. sensor, tried new computer, at a loss starts right up and idles great, take in down the road and starts surging. Exhaust? Why is my Chevy Blazer not getting gas? Pressing the gas pedal does not give it more fuel. Taking the throttle body sensor off makes no difference either. Took it to a mechanic for a "professional" diagnosis - they told me it...
