I'm not that great at cars yet so i need a little help on the facts of my car. I want to know if i have a posi rear-end or not. I want to know if my car is speed limited and/or rev limited. My car also vibrates really bad. I have huge holes in my exhaust right under the seats but i've been told that it had a broken motor mount. If anyone can help me with these questions PLZ do so.

 

If you look into your center console there should be a sticker with a bunch of codes on it. That is your RPO codes, here is where the decoder is: https://www.thirdgen.org/cgi-bin/rpo/index
That will answer a lot of questions you have about your car. You more than likely have a limited slip rear, which is stock. The vibrations could be a lot of things. Is your motor mount fixed? If you don't have the vibration fixed by the 1st come out to Hooters, I'm sure one of us could figure out whats wrong.

 

If its not in the center colsole, it will be in the back. Open your hatch and look into the storage compartment on the left. Mine is on the inside of the storage door.

 

thx for the help guys. i might see ya at hooters gator.
