2004 Taurus V6 Trouble Code PO174
 
Problem Solved............I have a OBD2 test result showing a PO174, which is a "System to Lean (bank 2) ". I have been unable to locate info on this code. Can anyone assist with what I can do mechanically to repair this. Check Engine Lightcomes back on soonafter clearing with OBD2. Thanks for any help! PeteUPDATE: I was able to locate info directing me to MAF sensor area and Vacuum Lines. I was going to remove MAF sensor to check when I noticed one of the vacuum tubes leading to/from the MAF sensor was disconnected. I reconnected and cleared TC. The cars runs 100 times better and no Check Engine Light!
