So I did the MPFI swap on my crx and it’s running, but it has a hard time keeping idle speed without stalling or back firing a bit. I’m using a PM6 L52 since it’s auto trans, with stock PGMFI intake off D16A6. I have B18 injectors. It has a 2.5” full exhaust with no cat. I’ve set my valve lash, checked it three times over, checked all my timing marks, set timing with timing gun, and went over all wiring and triple checked that as well. Can’t seem to figure out why it won’t idle correctly. The IACV has been cleaned and put back on. All new hoses and clamps for the entire cooling system. Could it be the injectors, not enough back pressure or something else I’m just obvious to at the moment? Any answers will help. I’ve used a PM6 A60 ecu as well to make sure it wasn’t just the ecu acting funny.

The ECU isn't throwing any codes?

Is the issue only with idle or does the problem persist at various RPMs and loads?
