ok so heres my problem found out why my car was running rich when the MAF is connected as soon as it goes into closed loop my long term BLMs drop like a rock to 112-113 and sometimes lower. Now heres the weird part with the MAF dissconnected when the car goes into closed loop my BLM's stay around 131-130 which is fine, so I thought the MAF was bad got a new sensor same problem, checked wiring its fine. So what hell is going on this is pissing me off after I finally figured out the cause I get a MAF and it does the same thing...any ideas? thanks
