I haven't driven the car much over the past 4 months but prior to January it was my daily driver. Since I've parked it I've done a little work on it that needed to be done.

Changed spark plugs
installed a new custom Y pipe and a B&B catback

and a few other odds and ends.

Last week I drove the car a few times and I can hear a rattle coming from the car. From what I can tell it seems to be located on passangerside toward the front of the car. I guess either the rear of the engine compartment or under the front passanger floor board. I thought it might be the Y pipe at first but the bolts on the flange are tight and looking over the exhaust I don't see any place that it's rubbing. I don't think this rattle was here a month ago but who knows now that the exhaust is quieter it might have been. All the work I've done has been with in the last month and the rattle is pretty loud. I can't seem to get the rattle to occur all the time it will only do it at times and sometimes when I slow down with the car in gear.

I just need some suggestions on items I could check.

Car has all the mods in the sig along with subframe connectors.

I had a rattle under my driver floor board... it did the same thing only sometimes... at a low rpm... and if i would go close to a building or drive threw u can really hear it.... which helps whith a loud exhaust.... so i took it to the dealership and they said that sometihng was messed up with the 02 sensor causing it to rattle.... fixed that problem....

Must have been the little shield on the sensors came loose.

Another common source of rattles are the numerous heat shields around the exhaust.

My SES light came on around the time that this rattle started but I replaced the 02 with an extra one I had from when I did my header install. The rattle is still there and it's loud enough that I can hear it with the windows up and the radio on. Someone else suggested a heat sheild too.

Is it a high pitched rattle or a dull rattle?

What was the code?

i think its time to start playing around with the exhuast... just try hitting it when its cool.... or if u have access to a lift put it in the air... hit it a few times if u dont hear it... start it up n try to figure out where the rattles coming from

Probably the metal piece that connects the 02 wire to the 02 sensor itself. Mine rattles from time to time.

It's more of a high pitch, like something is making contact or loose.


The code was P1153. I changed the O2 the other day.


I wish I had access to a lift but I guess I'll put it up on ramps again and see if I can find it. The problem is it won't just do it with the car running at least I can't hear it I have to acclerate to hear it.


Replaced the 02 the other day and I still have the sound. Seems a little loud to be something like that though
