Car idles fine but when i press the gas pedal bogs down. I have replace fuel pump, fuel filter, fuel pressure regulator, tps (adjusted it), plugs, plug wires, rotor button, and both temp switches. Runs the same. I was told that it could be the knock sensor. IS THIS TRUE? I also read that you can see if a knock sensor is bad by tapping on it with a screwdriver??? Please help. If i don't get it running by tomorrow they're going to tow my car.(FUCKING VIRGINIA!!!) My first 240 and i haven't even got to drive it. Thanks guys
