P0175 System Too Rich - Bank No. 2.........P2198 O2 Sensor Signal Stuck Rich................P2196 O2 Sensor Signal Stuck Rich

What does the rich part mean. I've been looking online. Something about the fuel. Any more info? I'll prob have to change out the sensors from the looks of it. Just want to more more about what it means

Some possible causes: (In no particular order)
1. Bad coils.
2. Bad injectors.
3. Bad MAF.
4. Bad fuel pressure sender.
5. Bad O2 sensors.
6. Wiring fault.
7. Bad PCM.
8. Internal engine problem.

Rich means that the O2 sensor(s) are seeing too little oxygen in the exhaust.

coils were change not too recently. Pcm e=was changed also cause i think i messed up its original one from running with bad coils for too long. I'll just wing it and try a sensor.Maybe injectors.I think i'll try sensors first. Its the cheapest thing on there right?
