What's the idle speed?
Does the power steering seem to be working OK?

im not sure what the idle speed is but while your foot is on the brake with it in gear you can hear the motor kinda bogging down. also the truck has no power until you get rolling. you cant power brake the thing on an icy road it just bogs down and another weird thing it has been doing is when I start it in the morning and it starts to do its idle up it'll get about half idled up and then start bogging for a second or two and throw a quick rev and start all over again
