Sorry, not enough question marks in the thread title. Go get more so we'll know you're really, really, seriously troubled.

If it's only dumping on one injector, you probably have a stuck injector or short in the electrical harness back to the PCM. If you're dumping on all four, O2 sensor would be my first step.

Dumping on all 4 and 02 sensor is new and seems to be working.
