Well im still fighting a miss in this engine and every day it gets worse. I have swaped wires, plugs, o2 sensors, cleaned maf & tb. started going lean in mornings, would do it once then clear up now if i run steady around 2000
a/f will stay 14.5 14.7 but if i run slow it will dip into the lean range and i can feel the truck surge. I now think maby injectors but not sure, my wide band is on drivers side so im thinking its on of them four. is seafoam in the gas better than lucas treatment? i need some ideas of things to try,
