I just started my car for the first time since I put the b18b in. Its a 97 civic dx. Both are obd2. I am getting 3 codes witch are 14, 65, and 91. The car doesn't have a cat and second o2 sensor so thats why im getting 65(header not connected to rest of exhaust). Don't know why I'm getting 91 and 14. I start the car up and it only idles for a couple of seconds then dies unless I give it gas, and the whole time its reving to 800-1700 rpm(crazy). Does anyone know what the deal is? Thanks for all responses.

 

Thanks guy I will try that
