I had same problem and it was the HFM . When they extented the wire for the supercharger install I ran into a problem with the HFM being the same deal as you . Oil I guess hit the HFM sensor and burnt it out . I got a new one and it worked ( I think you can check it by installing your stock air mass for a minute but dont take my word for it) Then after installing the new one I pulled the extended wires for the connector for the HFM and 1 puped out . Then I had the same problem again . I fixed the wire and I was good to go
I just got finished re-installing my supercharger after having it rebuilt. I double checked all the vacuum line connections and everything looks fine. But when I start the car, it will idle for about 3 seconds, stumble, then dies. I keep trying to start it and it keeps dying. Even if i try to hold the rpms at around 3000, it'll still eventually die.
One guess would be that before I had the s/c rebuilt it was blowing some oil (because of a bad seal) through the throttle body into the intake. Would this extra oil going through the engine this way foul up the O2 sensor?? The reason I say this is that right before I pulled the s/c, I got 2 engine codes that read: knock sensor cyls 1-3 and lambda control #1, which I understand are most likely O2 sensor related.
The car showed no more codes after I kept trying to start it.
Any help is appreciated.
