MIL = Malfunction Indicator Lamp -- also known as the SES = Service Engine Soon lamp

One more thing -- I just read over the techinfo again, it looks like each code will display *three* times before moving on to the next one. So you'll see 12 x3 - error code #1 x3 - error code #2 x3 - ... etc - then when it'* done, 12 x3 again.

If there aren't any codes, it should just flash 12 until you remove the jumper.

ok i got it, it continuiosly blinks the code 12, it blinks the service engine soon light once (I'm assuming that is 1) then blinks twice(meaing the # 2) 1+2=12 meaning code 12 but it just does that. SO....that means I have no codes stored???? But my supercharger doesn't work, I don't think it'* a lack of throttle smashing. any other Ideas

ahhhhhh

If it just blinks 12 forever, then there are no stored codes. Of course, that doesn't mean nothing'* wrong -- for many of the sensor circuits, the system will only throw codes if there'* a complete failure, like an open or a short.

I don't have a supercharger, so I'll leave the rest of the diagnostic suggestions to those that do

Where are you located? Can you put that in your sig? I'd like to see if you're near enough to another member to swap BCS'*. (Boost Control Solonoids). Your check gauges light being on during diagnostics is normal, as your engine isn't running.
