P0172 Trouble Code (system too rich bank 1)
Getting this code for the last couple days. I was told that replacing the 02 sensor before the cat would fix it,but it didn't. The other 02 sensor probably isn't my culprit because it doesn't really monitor the air/fuel mixture. The car idles fine when cold and then it starts to stumble a little when it gets warm.othere than the ses light coming on with this code,the car runs fine. any ideas?

maybe a leaking injector on the driver's side?

My mechanic found out that the MAP sensor was failing and had a vacuum leak. He replaced it and everything is OK now.
