hi, this is my first time, got a 93 k3500 chevy truck. When its really cold out (30 or colder) the truck runs fine.when you first start it, it runs rough, after you go down the road for about 20 minutes things get bad,this is if the temp. outside is above 30. the truck will start missing like it is starving for fuel, you play with the gas peddle for awhile and after a bit it will smooth out and run ok for some time the it starts all over again.I think I've replaced just about everything from the oxygen sensors to rebuilding the tbi . any clues????
