i have 96 integra ls and the check engine light went on this morning so i did a paper clip method and code i got 65 which is the secondary o2 sensor but when i hooked up the computer to the car it threw a p1337 manufacturing control ignition system or misfire and no code 65 o2 sensor came up. when i hit high rpms you can smell alot of gas and sometimes when i start it it will slowly start up i already did a full tune up like a week ago and oil change. so what code do i fix and how do i fix code p1337 ill probably do both and i dont know if it matters but when i bought the car it came with a b18a1 dont know what year though

 

so i found out that the b18a1 has this code when you put the engine into a obd2 car so thats why i have it and i can bypass it to clear the code. the code 65 is the secondary o2 heater sensor anyone know where that is located
