A few problems

[tmurphy12]

Hi Everyone,

I've had my Aerio for 3 yrs now and she is starting to become more trouble than shes worth. I was hoping maybe some of you folks here could help me with a few problems I'm having. Any help you could be with any of the problems would be great.

1) I am getting the P0420 code...does that mean I need a new cat or could it be a bad O2 sensor even fuel pump?

2)My OBD2 port (where you plug in the scanner) is not working anymore is that a blown fuse or does anyone know what else may cause that.

3) The fuse for the tailights keeps blowing out. I saw a post on here about that but it didnt mention a fix.

4) The AC works sometimes and not others...doesn't seem to be a leak.

5) The suspension makes some kind of popping noise on turns and when it first starts moving and going over speed bumps. It sort of sounds like an old flight of stairs.

Again any help with any of these problems would be tremendously appreciated. If I can't solve them I am going to be without a car mainly because of the taillight one.
