Before dumping alot of $$ on injectors, I would inspect the injector wiring harness thoroughly for abrasions, and bad connections.
See if you can get a OHM spec for the injectors and test them with a DVOM.
Get yourself a fuel injection pressure gauge and do a leak down test. Perhaps the injectors are not shutting off properly.
BUT, my money is on either a bad connection in the harness or a failure in the injector coil(s) internal to the injector(s).
