What is your question?
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?
thank you for your help. we had the spark plug changed and now it works super again.
