Bad o2 Sensors -aftermarket exhaust

Guys, my car is at the stealership for a 30k service. On the way over there, the CEL came on, no problem I thought, I am going to the service center... Anyway, the reading shows a bad o2 sensor, but they cannot repair/replace or confirm the error because I have a custom exhaust... headers, high flow cats, mufflers.

They recommend replacing all parts to OEM and run it stock to get rid of the code. I recommended they check in to the local psych ward. Since they cannot guarantee any results, my dilema is, should I just pay them to replace the o2s and risk the light coming back on? Should I shell out the money to replace the cats that they think are bad and replace o2s?

I don't want to restrict my system, as it is full exhaust, intake, and programmed. I also don't want to spend 3k dollars for a meaningless CEL. Otherwise, I can clear it myself and ignore it for as long as possible, but what is the downfall of running with bad o2 sensors.

I need to pick it up tomorrow or I need to tell them to repair it, i will be trying the other boards as well.

And the fault code(s) were....

He couldn't tell me when I went out there. He said it is "failing sensor"

Unacceptable, especially considering how much you paid for the codes to be read.

Sorry, without the fault codes everything is just a guess...

I know, If he doesn't give me the code, I can read it when I get the car back.

I am having a similar problem, aftermarket exhaust, car drives great, has constant CEL. Ordered a OBD reader, does anyone have a link to all the codes so I can verify if it is O2?

:rolleyes:
