I recently finished rebuilding my d16z6 top to botom a few weeks ago, and a few days ago i instaled a B&M command Flo fuel pressure regulator, and a AEM cold air intake system. I lefted my girlfriends house last night and my engine light came on. I checked and got a CODE 1 (Oxygen content). I turned my car off for a few min. started back up and no more engine light, no more code. I have been driving it like that ever since and the engine light never came back on. Could it be because it was really cold that night?? Im runing all PM3, ecu,dis and int I need to make sure i dont get no more engine light because im instaling my turbo kit next week.
