My truck cranks and runs fine at idol. It runs smoothly

Customer Question

My truck cranks and runs fine at idol. It runs smoothly until I get to 4th gear or so. The RPM RON is about 1500 and I am between 45 and 50 MPH. When I lightly press the gas the engine/transmission feels lilke it is you g to shake apart. If I press hard on the gas and the rpm goes up the vibration stops until the rpm drops to 1500 again.
Someone told me they had a similar issue on one of their trucks and it was a fuel filter.
