Well, I know for a fact it's an uh oh, I just need help diagnosing it. A few weeks ago, I did a 1st gear burnout, put it into second and let that run to about 5 grand. Got off it normally, and drove it home without hitting boost at all. The next day, I start the car and the CEL is on. So I think it's something minor, because there was no audible or visible signs of damage. Every time I go WOT or hit over 3 PSI, I get this nasty rattling sound. Doesn't happen if I have it in nuetral and rev to over 5k. I've heard this noise before coming from the supercharger, but maybe once in a month or two.. And even then, It would only do it for a very short period of time. My thought is a Supercharger bushing, or Possibly(I really hope not) a ring. The CEL is off ever since we put new brake fluid in and flushed it out, but still making that noise at boost.

Just recently, It started up misfiring with the CEL on. I limped it home. By the time I got back home, the CEL had gone off, and the car was no longer misfiring.

Any thoughts at all?
