So I replaced the #4 coil like the code told me (P0304) I also replaced the plugs. Now my truck feels like its gonna run out of gas and at highway speeds it shakes and feels like it will lightly stall (shakes at 1500 to 2500 rpm, stalls all the time) at times it feels ok but then it quickly starts doing it again. I think this might be the fuel pump or the fuel filter. Also the "SES" light is NOT on. Please help! I would like to drive my truck again.
thank you

Double check your wiring, read the codes (sometimes there are codes but no SES light).

Make sure your plugs are in right.
