so after having spark plugs replaced and wires, i got a check engine light on, thinking it was something small, i still went and got it scanned and it came up as misfire in cylinder 1. I had a mechanic from ford ride with me and let him drive it to see if he could feel it misfiring and he said he could and i could from time to time, he said maybe my spark plugs are gaped wrong or the wire isnt connected properly. would this cause such a code? how do i check for spark in the wire? could it be a coil pack issue? Im new to the whole 3800 scene so im trying to figure something things out.
