QuestionQUESTION: I have a 1997 dodge intrepid with a 3.3 engine.I have two codes coming up. The one code is P0174. It says left front system lean. Do you have any idea what that means and if there is a part bad and where it would be located? The other code is P0154 which says O2 sensor CKT no activity bank 2 sensor 1. Do you know where this sensor is located. P0154 only came up once but P0174 keeps coming up. Would P0154 make the other code P0174 keep coming up if the O2 sensor is going bad?
ANSWER: yeah I know what it means with that code alone U have 2 choices either A u can spend alot of money guessing to what the issue is or B take it to some one that knows drive ability and can narrow it down better using scanners and knowledge. this code has about 15 different causes.

QUESTION: Can you give me what you think the 15 different causes it might be so when I take it to some one I have an idea so that they don't just want to change parts to make money. This way I have a little knowledge about what they are talking about. Who would you take the car to? Should I take it to the dodge garage or use the garage that I use. Thanks.
