Headed to work today and noticed my check engine light was on...wtf?
Went back home and plugged up my sct and got two codes
p2196
p2198...o2 sensor stuck, too rich
Currently running a brenspeed 93 tune and have had no problems with the tune. Would the change in weather be the culprit? Cleared out the code and went to work and all is fine...any suggestions?

 

perhaps a tune issue causes thats both banks (1 and 2). how long have you been running that tune?

 

Although I've never had an issue with my Brenspeed tunes, I've heard where a few folks were running rich. If you began running that tune while it was still cool out, it could be the warmer weather. Let's see if the code comes back. It usually takes a good 20-60 miles of driving for it to show up if it's valid.

 

I had one that said stuck on lean, it sometimes randomly throws on because of long tubes and high flow cats, I just cleared it and watched, it didn't come back on. Sometimes if the sensors see the smallest change they freak out.

 

I get that code about once a month at cold start up. Got when I had a brenspeed tune and now get it with my JDM tune. Its irritating but nothing is really wrong. I think it happens because the cams pull extra fuel at start up or something like that.

 

Being cammed can be a bit irritating as far as codes r concerned. Mostly not a big deal as I feel my issues have been relieved. Like others say give it another try after u clear the code. Hopefully it wont come back and if it does u can datalog certain parameters that brenspeed may need to look at. Easy to do. Good luck
