2002 Ford Ranger Q&A
2002 Ford Ranger Question: My ford ranger idle fine, but when i apply the gas it bucks a little.
after about 10 sec it runs fine. as long as i apply the gas slow it will not buck. if i am going up a little incline or a hill it boggs down and bucks a little. in about 15 sec it starts to accelerate good. it will still buck now and then when cruising speed.i do not have any codes stored. - snooper1966
Good tune up should do the trick! Plugs, plug wires and possible coil pack as it can cause a misfire on one cylinder only! Sounds like you have a misfire causing the "buck" you mentioned. - pushrod
clean your throttle body real good, with throttle body cleaner from az or pep boys and add a can of sea foam to your gas tank and drive for a couple of days............brakestop and auto experts!!!!!! - brakestopinc
