Screeching sound

16NismoTech

So the car sat from Friday night till today at 3:30, drove it and the sound came right back, same thing it only happens when moving and off the gas. Just before I got home it tripped 2 codes, p2096 and p2098. For modifications I have the stillen long tube intakes, Tomei expreme exhaust, motordyne xyz pipe and aam hfc. Any ideas? Read up on the codes and I'm in the process of getting tuned but nobody mentioned anything about a screeching sound when tripping those codes.

I agree with the "probably a slipping belt" crowd. The belt may be worn or the idler is is not working properly. Easy to check with the hood up and someone working the throttle.

Edit: If system voltage drops when the squeal happens, it's a slipping belt (or an alternator bearing going out).

Put your nose under there and look. Hitting that much water puts a ton of force on parts that aren't designed for it. Could be as simple as a bent bracket. Also, you may have ingested a bunch of water into those cold air intakes. That can be very bad. Take off the cold air intakes before taking it to the dealer just in case. Good luck.
