i have a 2003 trailblazer ext. just had a tune up done on this vehicle. Cold starts it starts
up properly no problems. If i drive for a while and let the truck sit for an hour or two it is
hard to start up,it will crank for a few seconds then finally starts. I have no check engine
light so im kinda baffled on what it could be
