I have a 93 ranger 4.0 and I am having problems with hesitation during acceleration. The truck idles fine, but when i start to accelerate, it will hesitate until I goose the throttle all the way and then it takes off and starts running great. I have recently changed the plugs, wires, fuel filter, pcv valve and air filter. Someone has suggested to me it could be a loose wire at the battery, coil packs, egr valve, or a dirty MAF sensor... Does anyone have any advice for me? Thanks

Remove the TPS and test it with an ohm meter. Meter should sweep smoothly through out its range. The TPS tells the PCM (powertrain control module) what you, as the driver are doing to the engine.
sounds stupid but check your air intake could have small hole in it somewhere after the mass air sensor i had to make a cold air intake c ause of one i know put ducktape can fix it really check it out buddy:yes:
