Explorer PO174 code and suspension noise up front

[nestang]

Hey guys I'm sorry if theres already a thread for this but I have a few questions. First off I got a PO174 code and I'm wonder what I should do? Replace O2 sensors on the bank #2 or if it would be a bad upper Intake gasket or what?? I also have a noise up front in the suspension I believe like every once in awhile on a good bump wondering if its comon for like a ball joint or shock to go out PLEASE HELP!!! Also had problems with the top transmission line leaking goin into the trans, Im about to undo it and put a high temp locker/sealer on it and tighten it back up, i believe im goin to have to pull the trans dipstick to even have enough clearance to loosen and tighten it!

nestang,

i hope you know what 0174 means?
if you dont, its a basic "running lean" condition. doesnt really tell you much, unfourtunately.

some solutions are cleaning the MAF, checking your o2 sensors, and vaccum leaks.

hahaha yeah I know what it all means, just trying to narrow it to the common things, MAF is clean, gotta check o2 sensors, checked vacuum lines didnt find anything need to run a test to make sure. Just wondering what some of the more common deals are, its lean bank 2 according to the o2 only one bank for one which basically makes it impossible for it to be a MAF etc because it runs both sides the engine not just the Bank2 or 1 Ive read plenty on the subject just lookin for some people who been there and know what the hell there doing, thanks

hmm... you have a point.... mine triggered both banks, not just one.
checked your plugs and injectors? just throwing ideas out there.

havent checked the plugs but had a shop do em awhile back, could be there but I think that would have a more rich mixture there if there was a problem, Havent checked the fuel injectors but have ran plenty cleaners through, I wanna go threw and check each one with a dvom and see If I can find any problems there, IVe also read people having problems with the Intake gasket rings causing the same problem with only one bank. This is why im a fabricator and not a tech. I cant stand the dumb diagnoising and fixing it is alright if you know whats the problem most the time, but fixing peoples broken **** is not my type of thing lol but I do what I gotta there to keep up a couple daily drivers, My mustang is currently down since last night after some guy decided to pass me on the right as I was turning right on a 2 lane main street and he was haulin ass way over 25mph So sad theres about $1700 in just parts + theres gonna be labor and paint on top that but im gonna do all the work except paint
