this is an oxygen sensor reading that's saying that your left bank catalytic converter is not working at optimum range.. emissions problem.
the other says :Knock sensor #2 circuit low input (bank 2).
take the car into a muffler shop and have it looked at and tell them about the codes and ask them which sensor is the #2 knock you'll probably have to get the converter changed out anyway.

Have a 2003 Monte Carlo 3.8L engine. After I have been driving, I will come to a stop light/sign, and the car will stall out. Any ideas what this could be?


Check your IAC (idle air control) might be carboned up or quit working ,it in in the throttle body with 2 screws with a 3or4 wire plug, pull screws and clean the tip with carb clean and a rag, and clean the hole it goes in also and reinstall it and start it up and see if it took care of it, if not you might need a scanner to check codes and to read your sensors to see what isn't reading right.

I have a 2000 Chevy Monte Carlo with a 3.4l v-6. The check engine light comes on, and when it was scanned it says cylinder 1 is mis-firing. Is this a plug or wire issue, and if so, where is cylinder one...


number one should be first plug passenger side front bank. if you don't want to invest in a tuneup try swapping the wire with one from another cylinder and see if the misfire moves to that new cylinder.

2001 chevy monte carlo 3.8 liter v-6: starts fine


is your check engine light on ? if not check the fuel filter it may be plugged. it is also possible that your fuel pressure is low, is it start it then it bogs and dies, for you may have a defective idle air mixture solenoid, this will not call up a code there for no check engine light, hope this helps , let me know good luck
