I Have been told that the position of your wire on the 4.9L6 must be correct or there is a chance of jumping arc causing a misfire.

After being on the highway for a bit i get a slight misfire i think and my fuel mileage drops quite a bit.

I just replace everything from the Coil, wires, cap , rotor, and modual.

If someone has a photo of the position of there wire on the cap that would be awesome or any other advice.

Thank you
