my excursion has been acting up since i used gas from a different gas station. my suv seem to be bogging and when i pressed the gas it shakes alot. i bought a matco code reader and it said something about cylinder 3 and 7 misfiring. is this the cause of the gas that i used? is this why my suv shakes alot when i try to go 50mph?
code reader p0307 and p0303 on 2000 Ford Excursion

Sounds like you have two cylinders out of eight misfiring, your Excursion has one coil for each sparkplug you could have a bad coil or needs a new set of plugs, your vehicle calls for Autolite double platinum with a .054 gap
thank you for your help. we had the spark plug changed and now it works super again.
