Or is it like the EGR issue w/the Phase 1 EJ25>>EJ22 swap, which will give a CEL w/out the EGR?
Edit: And does the EJ22 still work w/either the MAP or MAF-based system? I know I can swap intakes (thanks to 'subaru360') on either the 2.2 or 2.5, too.
Based on Wikipedia and a couple other sources these EJ25 SOHC engines came w/either MAF: EJ253 or MAP: EJ251.
And what's weird is they weren't consistently applied. The '99 EJ251
(MAP), was replaced by the EJ253 (MAF) in '00, and returned in '05??!
Thanks for any clarification.
