I have been getting a p0132 code recently, no red check engine just an occasional cough on acceleration. Started checking codes and this is only code I got.

Harley dealers I use diagnosed a bad fuel injector about year and half ago they for some reason took my power commander plug in diodes that come with the set up out of the wire connection that would normally be connected to the o2 sensor and just reconnected up wires as they come stock to the bike. In other words reconnected the o2 sensor wires back to stock....My bike is a 2008 ultra with 255 cams a power commander 3 fuel management with now fuel moto exhaust slip-ons i use to have Rinehart slip-ons. The bike has been dyno tuned professionally by Rob's Dyno in Gardner Mass.

Guess what? code went away....bike seems more responsive. Anyway if this may help anyone with same issue hope I have helped.
