Answers :

BARO: Barometric--MAP--Manifold\015\012 Absolute--and EBP--Exhaust Back Pressures: All three should indicate \015\012atmospheric pressure (14.7psi at sea level) and read within 0.5 psi of \015\012each other, Key On Engine Off.

Good luck and take care.

Do rate this solution.
The exhast should always flow freely
\015\012If a back pressure is your trucks symptom it is more than likely caused by a bad MAP sensor, o2 sensor or a plugged catalytic converter
