I've got a feeling it will, the oxygen sensors tell the pgmfi how much oxygen the exhaust is putting out and it adjusts fuel/air mixture into the engine. Your check engine ight wil be on all the time too.

i thought that the only o2 sensor that reads air-fuel is the primary b4 the cat, the one i will put on. i was wondering about the one after the cat that tells if the cats clogged or what not. frickin obd2..anyone know?
