Alright thanks for your input guys. I changed the plugs yesterday myself after a good lunch at school haha. The plugs were pretty burnt, I'll be uploading a picture tonight. Previous plugs were Bosch.
I threw in the NGK and the truck runs a lot better now. Before I was experiencing a slight misfire/hesitation when trying to accelerate slowly from coasting speeds, and last night I drove the truck pretty long and pretty hard and noticed a slight performance increase even in the shifting and snappiness of the throttle response. Think the burnt plus could've been the culprit? Another thing is I've got the service engine soon code, it's been there since June when I bought the truck and I ran it on the code reader. I guess bank 1&2 were running too lean... That's where the worst plugs came from, any chance this is why??
