Ok so i have 07 420 4x4 that came in with hard cold starts so i adjusted the valves and now it cranks better but the throttle hesitates when u floor it ( i dont remember if it did it before i didnt drive it much beforehand)
Anyways it pops and back fires and dies out at random . I did a comp check and its reading 60 i have checked and rechecked the valve adjustment and changed the plug and i am at a complete loss and ideas.....
