P0134 CEL Light?

[Darksun280]

For me I had p0133 for a week then a p0134 this morning and now the cars running 10.0 a/fs I mean it's kind of a no brain-er it's the 02 sensor. Even more so for me cause I've had vp, sunoco, and cam 2 race gas in the car on occasion. I think the sunoco killed mine.

I ended up replacing it with a used one, then a few days later my rear tire blew so now my car is sitting in the garage waiting for my new wheels/tires to show up. Basically the code would come on every few days and when it would come on the car would immediately have AFRs of 10.0 during cruise and they'd stick there. After I reset the code the car would be fine. The sensor was somewhat heavily covered in black soot (sp check?) but the wires were fine. I ended up swapping it out anyways, hopefully that damn CEL doesn't come back on again.

Did the code show back up in the time between when you changed the o2 and when your tire blew?

Nope, it sure didn't. And in between that time I made a 3-hour drive to my parents place (which is where my car is stuck at the moment ). I'm hoping it doesn't do it again, it does usually take 4-5 days between the light popping up again. This last time, before the tire blew, it had been 3 days.

Well I'll be crossing my fingers for you. Im guessing that your problem is solved, but post up your results either way.

Yeah, o2 sensor goes bad and it affects LTFT, takes usually X # of cycles of the ignition and/or 50ish miles driving to kick the light on once it's been reset.

My STi used to do the same thing when the primary O2 failed, then again after I replaced that my MAF was bad too, but had to rule out the cheaper fix first

Is P0134 the same as P0137? I'm getting P0137 and it has the same description as this code. How many sensors are in the exhaust? One in the cat and one in the downpipe?
Seems like these sensors go bad fast with aftermarket exhausts. I only have 26k miles on the car.

Just got a CEL last night and got the code pulled at Autozone this morning.. P0134... Have bolt ons with 21k miles. Going to check the wiring and the sensor itself today, but am prepared to buy a new one based on what everyone here is saying. Looks like I should at least get it cleared so I can get better fuel economy until I can fix it haha.

I have been getting this code as well. Well, p0133-134. I did a boost leak test and had some leaks. Codes were still there and now have been tuning with Hollywood and that code is no longer popping up. Hoping its fixed cause those o2 sensors are pretty spendy
