P2127 SET AFTER PCM REPLACEMENT, COULD THE TPS NEED CALABRATED

What is your question?

i REPLACED THE ECM AND NOW CODE P2127 SET AS A HARD CODE, NO OTHER CODES STORED OR IN HISTORY WITH KEY ON ENGINE OFF I READ DATA AND WHEN GAS PEDAL IS DEPRESSED READING FROM TPS APPEARS TO BE CORRECT.

What makes this problem better or worse?

SLOW DRIVING AND RIGHT OF IDLE ENGINE STUMBLES

How long has your 2003 Dodge Ram 2500 had this problem?

A COUPLE DAYS
