What happens when a car has the code p0171?
Driving a car with the code P0171 can cause more damage to the engine over time, as when the engine runs lean, the combustion temperature is higher. When an engine runs lean it lacks power and may stall when the car is stopped at a stop sign. The acceleration may also feel slow. An engine may run rough at idle.
When did my Honda CRV start stalling?

If the problem persists the front oxygen (O2) sensor may need to be replaced. The P0171 code could also be caused may be caused by one or more of the following: debris on MAF sensor causing an incorrect reading, improper oil level, low or high fuel pressure or Engine Control Temperature (ECT) Sensor reading inaccurate.
How much does it cost to repair a p0171 Pontiac?

How can I tell if my car has a p0171 trouble code?
Assuming that no other trouble codes exist, a mechanic may diagnose the P0171 code by checking the engine for vacuum leaks with a vacuum gauge. A vacuum leak will create a hissing sound usually only audible when the engine is turned off. The fuel pressure sensor and MAF sensor (mass air flow) will also be checked with a fuel pressure gauge.
What does p0171 system too lean Bank 1 mean?
P0171 System Too Lean Bank 1 Technical Description. System Too Lean (Bank 1) What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code.
