Hey guys, this is NYb16, posting as my brother, ive been boosting a few days now and the other night i threw a code...engine code 1!?!?!?! oxygen content? wtf does this mean? im running a test pipe with the secondary o2 sensor wrapped in foil. i dont know if these two have anything to do with each other

 

Are you sure it's code 1? Code 1 is 1 quick flash. If ithe CEL is on for 1 slow blink, it's 10 (intake air temp sensor).

If you're getting code 1, it's your promary O2 sensor. Do you run a lot of race gas (leaded)? You O2 sensor could have went back. First check the wiring to make sure nothing is cut or fried, and if that doesn't help, go rob an O2 sensor off a friend's car and see if the code goes away. Good luck.
