my car is throwing a check engine, so i hooked up my AP, and it says code P0031? any idea what this is? on the cobb website, they say that it can show up from a low octane gas, and possibly the engine is misfiring. i guess it would be a good idea not to push it right now.
after a quick search on Nasioc, I came up with: P0031 Front oxygen (A/F) sensor heater circuit low input hopefully, that's all there is!! http://forums.nasioc.com/forums/showthread.php?s=&threadid=185275
sensors fail all the time. you know you get a discount at SoG off parts, right? I'm not sure which sensor you would need, either WRX or STi, since you have a swap done...
yes sir... and now the leak from where the DP and the midpipe meets is REALLY bad... i dunno if that is the one that is causing the sound, but my car sounds like a helicopter... but it's kind of weird because it will only sounds like that when i`m traveling at over 40+ mph.. it wont do it when i`m just standing still and reving it.. maybe it is something else, and if it is, i`m going to be pissed i hate the fact that my car is soo old.. it cost more to maintain than to mod...and it doesnt help when you have NO money..
