It sounds like you have an enormous vacuum leak. Is you PVC connected to your intake. I hope you get it fixed but it does not sound good. with 2000 miles on the motor I would have to wonder it you may have to pull the motor and go through it. If it ran that rich its probably ruined the bearing with gas in your
oil. How did it run that rich? I thought fuel Injection was suppose to be more precise than a carb. I have AFR heads also and the quality of the heads is second to none. I thought blue smoke on decelleration was because of the rings? I had a 302 that smoked when the PVC hose came off but thats a dam lot of
oil for a new motor.
