Hi, my name is Amanda. I have a 2002 9-5 Aero 2.3L turbo.my check engine light is on and when I took it to my local auto zone for a diagnotic test it showed the followingefinition- Code P1181 indicates that the PCM detected that the long term fuel trim for bank 2 remained "lean" for a predetermined period of time. The Error codes Read are as follows1181- Long term fuel trim additive max value air/ fuel too lean, P1260- Fuel Pump speed relay control circuit, P1261- Throttle binding,P1251-Check engine lamp, Output from control module low, and P0304-Cylinder 4 Misfire detected. My questions are: What do these codes exactly mean? How much would it cost to fix them?if you could get back with me at your earliest conveience I would greatly appreciate it. Please and thank you. I really love my car.
