FRS/BRZ Direct Injection Question
 

I have a question. What happens if the direct injectors are not installed in the order they are taken out?

I have a built IAG block/head combo and I'm trying to chase down some misfires on idle.

I had the port injectors cleaned and everything by Southbay Fuel Injectors however i have no idea if the shop installed them in the order they were taken out or if that would call for a missfire.

Any help would be appreciated.

I installed totally different, freshly cleaned injectors with new seals and no care for order or the number on the injector.
Is the misfire limited to idle or does it get more intense with RPM / load?

Maybe not related but a lite weight flywheel has been known to cause misfires at idle.
