SOURCE: trouble code 0171
P0171 OBD-II Trouble Code
google_protectAndRun("render_ads.js::google_render_ad", google_handleError, google_render_ad);
System Too Lean (Bank 1)
What does that mean? Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.
Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.
Symptoms You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.
Causes A code P0171 may mean that one or more of the following has happened:

You have checked the fuel pressure? Do you have a check engine light? As for the tank filling up the wrong one, that is caused from a bad tank select valve on the frame rail.

Testimonial: "when ive checked the pressure it was good, and ive replaced the select valve maybe its defective, thx man"
SOURCE: This car has 51,000 miles.
All I am getting from your discription, is that you
have a code & a misfire ,you have yet to diagnose.
Except for replacing the wires, that should last the life
of the car,your doing okey
You now are embarking on throwing parts at it,
I can't tell you how to continue,as I don't know
if have any test equip or skills required.
You may have a bad ignition module or other
Again,test,don't install 1 part,unless something
