Default Rough idle
Hey guys I got my 2012 f150 Harley Davidson with the 6.2. I just started getting a rough idle anywhere from 400rpm to 1200rpm only at idle. Runs great any other time. No misfire codes but I have been getting a P0155 code for catalyst. I知 thinking my cats are stopped up but I知 unsure.

P0155 is bank 2 (driver side) sensor 1 (front sensor). Typically a cat issue would trip for the rear sensor. I would start with this
