My CEL is on and I had it scanned at local parts store and the codes were P0171 and P0174. These codes corespond to Bank 1 and Bank 2 and are lean codes. Also my car will lunge forward when I stop sometimes. At first I believed it to be the O2 sensors but after further reading it might be a vacuum leak, the air intake hose or my throttle body needs cleaning. Are there any mechanics out there than can help me? My car is a '04 Mazda 6 with around 70,000 miles.
