i have a 1996 Chevrolet z71 305 it started bucking so i pulled the codes and it said the cam shaft positioning sensor was bad so i changed it and drove it and it was a little better but still slightly bucking so i pulled the codes again and it read mass air flow and map sensor code showed up im just wondering whats going on.

if you are getting multiple codes from different areas, check the battery. IF the battery is no good then it won't allow the computer to operate correctly. Then check the hose to the map sensor to see if it is soft and collapsed as they did this. Charge teh battery though and take it to an auto parts store, they can check it.
