Here's my predicament. I have replaced the fuel pump, fuel filter, air filter, rotor, cap, plugs, plug wires, ignition coil, and most recently the engine coolant temperature sensor. My car seems to be using an extremly rich amount of gas (can smell) and gives me three trouble codes. 1-1-3 1-2-3 and 2-2-1.
113 is Fault in fuel injectors, 123 is fault in signal from engine coolant temp. sensor and 221 is fuel system compensating for extremely rich or lean running at cruise. I have replaced the engine temp. sensor and tested (works) but still get the code/codes that I was getting before. I have checked the fuel pressure regulator (can't blow through it, no gas in vacuum line, shoots gas out when take return line off etc.) Can anyone help me. Someone said to clean all the injectors with special ammonia stuff but that wouldn't explain me still having the coolant temp. senosor code. Any help would be appreciated guys. I've spent over 30$ on gas since last Friday. Thanks for any help guys, Steven
