Welcome to the forum.

This is the 4th Gen Ram section for 2009-current Ram trucks. The 1999 Rams are 2nd Generation trucks. The 2nd generation goes from 1994-2001. Maybe a moderator can move this thread over there for you, get you some better answers from guys with 2nd gen experience.

Did you disconnect the battery for a long while after replacing the TPS and MAP sensors? The computer may be looking for the old sensor, and not used to the new one. I had a 2001 (basically the same truck) that did the same thing when I replaced the TPS sensor. Disconnecting the battery for a long while will reset the computer and may fix it.
