hpefully this is nothing to worry about, but when I was driving the other day I herd a little ratteling noise only when the engine is around 3000 rpm and just entering boost. It is not there at WOT, or idle, or full boost, or no boost. Just one little area where it shows up. Almost sounds like something is lose or a screw is rattling, or something is rubbing, Please help me out whith this.

Sounds like detonation... you may have gotten some crappy gas. Put in some good premium, and possibly some octane booster to help out the stuff thats already in there. Have to be real paranoid about detonation, its a killer.

 

So that's all that it probably is?

 

Another thing to possible check out is your spark plugs. Make sure they are note working them selves out. Its better to check them and make sure than let them fire out your head.

 

Dan,

Call Jim and discuss with him.
