New Injectors and Distributor, Now Random Misfires

I'm using these 30lb Bosch injectors set up for a TPI system. They have special spacers fit to the tip so that they fit just like OEM ones. Without the spacers they barely sealed like you described. These ones fit tight and no sealing issues.

The ones I have use similar adaptors to those, but from fuel injector clinic.
