When my truck was idling in the parking lot it started to buck. When I left and drove up the hill or applied pressure to the gas peddle it started to buck again

If the check engine light is on, have the computer scanned to identify trouble codes. Most parts stores will do it for free. If it isn't on, check for vacuum leaks and check fuel pump pressure. If you haven't tuned it up in a while, you may want to check it for a tune up.
