Ok, I have that a/f mix problem. I am going to do the tests I need to do, BUT i was thinking if the ECU ends up OK but I still have a problem with the car starting and a/f mix, can I use an intake off a d15 block and put it on the ZC motor and it work just the same? I don't know what kind of intake I have on my engine now, as it was on the old motor I did the swap with. Will it work though? Can I still use the PM6 ECU with that intake? I'm just trying to think of a way to get the car to run right!!
