    I have a 99 pete with 3406 E cat it started missing today on a pull. I stopped in the pete shop in little rock but they were too busy but they thought it was the o rings on the injectors or a fuel line sucking air. can anyone help?

    O-rings on injectors cause other problems other than missing on a pull. You may just have a bad injector. When was last time overhead was done. If it has been a while try a overhead adjustment and get a cylinder cutout test done at the same time to see if adjustment and weak injector are the same cylinder.
