1990 Plymouth Laser TPS & Barometric Pressure Switch

Ii have got a 90 model Laser with a 91 model motor. iI bought a rebuilt computer for the 91 motor. The problem I'm having is that I am showing a CES light. The codes come up as TPS sensor and Barometric pressure switch. I have bought a different MAS sensor, and after putting it in its still throwing the codes. Any ideas as on how to figure out how to fix this so it stops throwing the codes would help a lot!

THANKS!!
