ok i figured out which plug it was it happened to be blue not grey and i got code 43 fuel system supply code i have a new fuel filter, I think it could be one of my injectors just not sure

 

Also if this helps my gas mileage kind of sucks

a bad o2 sensor can still cause a cel 43 and bad gas mileage

 

guess its worth a try since the o2 tells the ecu how much fuel to dump in the engine

 

but what about the jerky acceleration?? fouled plugs i guess?

 

o2 sensor solved my problem no more MIL thanks alot
