Exclamation 2003 GT P0174

So, it started running this code last week, the bank 1 air bank on the passenger side, last week, I know it is running lean... I need to know how to fix it, cheapest possible, as this is my first Pony, and I am a high school kid on a budget.. So if you have any ideas, have had this problem, or anything else that you possibly think could help me, please share!! Thanks!

Check out the o2 sensors, they aren't to expensive, plus save you some money cuz that's pushing more fuel and pushing your gas mileage down. Should be the one right in front of the cat on the passenger side. Let me get back to you with a 100 percent for sure answer

Alright man, I'ma put it on the lift in the shop next week for sure, and will start a more in depth search for the problem. I'm gonna check all my fuel lines too makin sure we ain't leakin or nothing else that could cause this. Just hoping it ain't too major..

Re: 2003 GT P0174

Long overdue update... But we went and looked at it, and i had an exhaust leak. The LFTRIM(2) was at 24, and the SFTRIM(2) was at 27. After fixing what we believed to be the leak, the SFTRIM(2) dropped down to 7ish, and played around there, although the LFTRIM(2) was at 24 at idle rpm's. As rpm's increased, the numbers dropped. Waiting to see if the light comes back on. Hopefully this fixed it!!!
