Yesterday when I was driving home I got the service engine soon light when I passing a car on the hwy. Today I took it to autozone to get the code read and it came up as P0137. The guy told it had to do with a O2 sensor. Now my question is could this be the cause of the SLP? I had the exhaust for about 3 weeks now. If it is the O2 sensor what are some of the side effects I should encounter?

Thanks in advance.

How many miles do you have? It's possible that the O2 is getting crappy after a lot of miles.

The SLP shouldn't effect it because the entire system exists after both O2 sensors and the cat.

P0137 = Oxygen Sensor Circuit, Low Voltage (Downstream sensor)

What would cause this to happen?

faulty sensor in your exhaust system, could be related to your upgrades, i'm not to sure, maybe make sure then are all the sensors are in place??.......check around the forums, and see if anyone else has a similar problem.....that would be your best bet, if no one replies to this thread
