So I am starting to get into cars (I’m a noob!) and I own a ‘13 FR-S.
A few problems I am having with it:
-Squealing noise when I start it up in the morning (30-45 degrees) not sure what it is??
-Check engine light, says it’s the o2 sensor, the o2 sensor has been replaced twice and it’s burned them up. I do not have a header but I do have a Borla axle-back exhaust on it ( pretty sure, haven’t jacked it up to see what exactly is going on under it ) . I got the car modified like this and not sure if it was tuned... or if it even needs a tune. I’ve been to multiple mechanics

Manual transmission? If so the squeal is probably the clutch throw out bearing. If it is starting to go it is always the worst on startup.

Axle back will not cause an O2 sensor issue. Positive there isn't a header?

It’s automatic

And there is no header, I’m positive

Hello Jared.FR-S and welcome to ...... The Forum .......

On your next cold start, I suggest you open the hood, lean over the engine, have someone else start the car and see (hear) if you can isolate where the squeal is coming from.

Since your car has an AT, my guess would be a lose serpentine belt or a bearing in the idler pulley or A/C compressor or the alternator.

The axle back muffler shouldn't require the engine to be "tuned" nor should it cause a O2 code to be thrown.

Sounds to me like you got someone else's shity tune. Contact previous owner ask them what kind of shity tune they put in there. Once you know bring everything thing back to stock factory settings.

The start up wine could be a lose belt. I guess since there is no vid or something.

You could try an o2 sensor defouler, they are a super cheap option they may help ya'

That will fix the light but what if that leads to damaging something else?

Could be caking up your sensors by running too rich.
Or burning them out by running too lean.
Can be caused by an aftermarket exhaust your car doesn't like.

Try and find out if it was retuned...

Jared.FR-S · 12-30-2017, 08:28 AM

Update: So the car was never tuned. So now what?

Are you replacing them with aftermarket 02 sensors or OEM ones? Also, no other codes? And how many miles on the car?

stevesnj · 12-30-2017, 12:54 PM

Squeal could be a bad serpentine belt.
