I will test the resistance on the ones that came out in the morning. The problem seems to be with the same injector (the one in the middle of the front bank), even now that it has flared back up. So a connector/ecu/wiring problem seems more likely than a bad injector ( I admit that it is still possibly a bad injector, just not likely). I think I saw a thread with a similar problem that may have been solved with a cleaning of the connector to the injector.
