Supercharger Problems?!?!

[Dark Runner]

Im rockin the 7th injector and have had this set up for over a year now and all of a sudden, I got a check engine light. Obd2 said I was running lean, so I checked everything on my intake first finally i took off my supercharger as a last resort today and sure enough, the check engine light went off. I have no idea how this is possible. Fuel pressure is fine, fuel injectors, fuel filter and pump checked out just fine. AHH im losing my mind. Any suggestions, please!!!

maybe a bad o2 sensor?

Lets start w/ what air fuel does your wideband say you are running? when is it leaning out? do any of the spark plugs shows signs of running lean?

Go to customtacos or yotatech forums for your S/C questions.

This is weird, my a/f readings are malfunctioning. My o2 sensors are fine. the spark plugs are deffinately burned and corroded from lean.

by the way, I am running the 2.2" s/c pulley.

Is it possible that the impellers are malfunctioning and some how forcing in too much air?

The MAF is the only thing left that think could be messed up but all my computer says it working fine

What do you mean your a/f reading are malfunctioning, are you running too rich or too lean? Very first thing replace all spark plugs and if you are running to lean you might try narrowing the gap. How old are your coilpack and wires? Are you running 93 octane?

Impellers forcing in too much is air not really a possibility (IMO), but this is why you should have a boost gauge or data logger to moniter.
