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

 

its the maf clean it and if it doesnt fix it replace it. do you have a check engine light on?


i had the exact problem and i changed out plugs and wires, fuel filter and checked all my connections and finaly i got a new MAF and it runs great
