I have a 99 GTS with a 10Lb Roe S/C on it. It has Ballenger headers,high flow cats and Corsa catback, Vec 2,water **** and Dual Walbro fuel system. CEL came on and it was code p0174- too lean on bank 1. Also had another code for the evap system, but I don't remember it. Cleared the codes but the Car still runs "rough" and seems bogged down, My AFR gauge is also reading richer than normal (sometimes 10.00). I'm sure the ECU is dumping fuel in since it sences a lean condition.
Could it be a bad cat?
Bad o2 sensor? I figured it would throw a different code though. Is there a way to test them?
I've never data logged with the Vec 2, but I don't think I could anyways since the computer sits under the hood and I don't have a serial port on my computer. Can you data log on to a smart card? I'm guessing not, but I really dont know.
Any ideas or suggestions?
Thanks
Colin
