Another problem with the supercharger

so after i figured out what happened after i bottomed out.. it was just a leak in the oil fuel line.. no biggie got that fixed car drives fine.. today i drove around for 30 miles and as i was heading home..as i was stopping to a stop light... my car stalls when i was in neutral... i start it up.. it was fine.. then i kept driving.. when im in 1st gear.. the RPM keeps jumping from 0-1000.. then it would eventually stall.. i have no idea whats wrong cuz it was fine the past couple of days.. and then i realized the Check engine light is all of a sudden gone.. and when my car is in neutral the car idles really wierd.. jus always seems like its about to stall.... what could be wrong this time??

I had a similar problem on my car. Took it to the dealer and they had to replace the Throttle chamber. Although your car has a SC and my car only has cosmetic mods...for now =] it might be related to your performance upgrades. Not sure. But the symptoms match.

Check your vacuum lines running to your BOV and to the SS box

If it was the blower .....you would hear [ in most cases ] a very loud metalic noise . The blades hitting and scraping or a granding of gears. If the seals were shot , you would have oil coming out of the blower .

But again....its hard to say over the internet
