Recently I have noticed that my p/u when cruising at 60 or above begins to hesitate and bucking so bad that I have to shut the car off let it sit and then drive again and then it does it again. Then if it sits for a while it runs fine for a few days and does it again.: So far I have noticed:
1) Has done it with full tank of gas and almost empty 2) Dry and in Rain 3) I only notive it on the highway (most of my driving) 4) I changed the wires and plugs 5) I?m not sure if it always does it when I?m cruising at then accel. 6) Seems it gets worst the more load I put on the engine. 7) I can put my foot down on the gas and the car just doesn?t move. But when the car idles its fine. 8) The hesitation is like a bucking horse!!Thanks for your help!
