my truck has a bad miss i changed the plugs and wires and i also put in a new fuel pump about two weeks ago it has a slight miss at idile but as soon as i put it in gear it worsens and when driving it will line out for about 20 seconds and then start to bog down and miss again it also backfires when the truck shifts any i checked the dist.cap and rotor and they seem to be fine i did replace them about three months ago any sugestions
