Hey everyone I’m currently fighting an issue that I can’t really find any info on. I’m using a 05/06 ktuner prb ecu and 05/06 base harness in a k24a2 swapped civic. I have a cel for p0603 and the car was in limp mode. I checked all my grounds and charge harness over 20x and I had two other people look at it also. The other day I switched maps from k24 to k20 and limp mode was gone but car is really sluggish and breaks up but code p0603 is still there. Any info is greatly appreciated.
