Truck started "bucking" at about 35 mph. I tried to accelerate and it got worse. I took my foot off the throttle and it stopped. Then it seemed fine. A few days latter it happened again. Now at times it feels like it running a little rough. Most of the time it runs great. Any ideas?

This happened to me once and it was a loose battery connection.

does it almost feel like it is running out of gas? and you might try checking the plugs

New plugs. It still wants to do it. At about 1500 RPMs. Runs great at higher RPMs. No codes, I cant figure it out.

my truck dos this everyonce in a great while.. IT seemed like it was around 35-37 mph. But it didnt do it often enough for me to worry about it.. I did recently change my plugs so maybe that helped
