Yes I am aware those would not effect spark an are a separate issue, probably something to do with fuel mileage dropping past 2 month's. I checked for voltage going to coil an it was ok. Checked the ohms on the crankshaft position sensor an it was 800 a little high. Kinda lost at this point. Coli has 2 separate coils an both would not just stop at the sane time is what makes me think it's not the coil.
