Question about 1996 Ford Escort 4 Door
Hello, Its possible the noisy injectory is a problem. The code p0171 is a lean code. This usually means there is a Vacuum leak allowing more air into the engine than fuel. You can take a spray bottle of water and mist the engine while it is running. When you come across the part that is allowing more air into the engine, there should be a RPM change. Fix the part you find.
Usually the p0171 Code is an average of all cylinders on 1 bank of the engine. You could easily have a clogged Injector making the fuel mix lean. There are some kits in which you attach a tank of cleaner to the fuelrail and run the engine on the cleaner until it stalls. You will need to ask an Autoparts store if the kit is available.
In any case, reset the trouble light after making a repair.
