Diagnosis please

4.6 is bogging out (whole car starts vibrating) for short distances of 4-8 miles randomly over the last few weeks. It's not a tire or suspension problem because when I depress the clutch it immediately stops vibrating so it's def the motor/transmission.

2 times it was right after a fill-up and 2 other times it's as the tank is getting pretty low.

Correlation or coincidence?

Change the fuel filter and see what it gets ya.

I'm assuming you have no engine codes?
