I resealed all 4 injector cups on the drivers side today. Inspect the injector cup seat and head surface for cracks or warping. I think i am having similar issues about to have it torn down, my mechanic seems to think i am vapor locking and not actually having injector.

You can try to reseal the cups and put it back. Finally tore into it today thinking if the injector cups look good ill go down to the head gaskets. Leaky injector cups and a head gasket issue can present the same symptoms on an lb7. Both injector tips had rust on the ends where the others did not.
