Engine Performance problem
2003 Chevy Tahoe V8 Two Wheel Drive Automatic 103k miles
I keep getting errors P0102 MAF/VAF circuit low input, P0171 Bank 1 system too lean, P0174 Bank 1 system too lean. I've found 2 of the oxygen sensors located by the catalytic converter but have no clue where the others are located up towards the engine. Also the car is running rough during cold weather but with warmer weather runs a lot smoother. Any suggestions you can give me would be greatly appreicated.
