my 1994 f150 has 180,000 miles on it with a rebuilt transmission and it is bucking/jerking while driving at any speed cannot find the problem thought of everything what could be help me please.

 

I'd start with a complete ignition tune up if you haven't already done so. Rotor, distributor cap, spark plugs and spark plug wires. Also put a container of fuel injector cleaner in a full tank of gas.

 

ok thanx anything else you can think of let me know.

 

Just buy a rotor, distributor cap, spark plugs(Autolite or Motorcraft) and spark plug wires. Buy a spark plug gapping tool and check the gap, the spec be under your hood some place, around .042 or .045 I think. Buy any other tools such as a spark plug socket, ratcet and extensions if you don't have them. Get some di-electric grease to put on the rubber part of the spark plug wires where they slip over the spark plug.

 

Check the wires around the exhaust pipes and around the bell housing and fire wall. Something could have gotten pinched/burned when the trans was put back in. That's my 2 cents!
