I currently own a 2003 SLT 4x4 short box reg.cab with the 5.7. I will be driving down the road and the ETS light will come on (throttle sensor) and the truck does not accelorate properly. When the truck is shut off the light will go out and the check engine light will stay on but the truck drives normal again. Every time I take it to the dealer they just reset the check engine light because they can't re-create the problem and it just happens all over again. Can anyone give me any feedback into why this is happening or what I can do to fix it? Thanks
