2002 Ford Windstar Check Engine DTC P0171 "System Too Lean"?? Help

Hi, I pulled up this code P0171 because my check engine light is on.

Can somebody tell me how to start trouble shooting the problem??

Here's what I looked up so far:

P0171 - System to Lean (Bank 1) The Adaptive Fuel Strategy continuously
monitors fuel delivery hardware. The test fails when the adaptive fuel
tables reach a rich calibrated limit. For lean and rich DTCs:
Fuel system
Excessive fuel pressure.
Leaking/contaminated fuel injectors.
Leaking fuel pressure regulator.
Low fuel pressure or running out of fuel.
Vapor recovery system.
Induction system:
Air leaks after the MAF.
Vacuum Leaks.
PCV system.
Improperly seated engine oil dipstick.
EGR system:
Leaking gasket.
Stuck EGR valve.
Leaking diaphragm or EVR.
Base Engine:
Oil overfill.
Cam timing.
Cylinder compression.
Exhaust leaks before or near the HO2Ss.
A SHRTFT-1,2 PID value between -25% to +35% and a LONGFT-1,2 PID value
between -35% to +35% is acceptable. Reading beyond these values indicate a
failure.

I need a trouble shooting flow chart!?? I have a 2002 Ford technical publication but I can't find any flow charts on it.
My email is: Johnny916@aol.com and it would be MUCH appreciated if somebody could send me something.

Search this forum...............P0171 is the most common code for Windstars and the troubleshooting of it has been discussed many times over.

do a vacuum test to see if you've a vaccum leak.
this is what I had in my 99 Windstar.

Through PCitizen's link, you will find detailed step by step pictures and instructions of making this fix. It is such a common problem that Dorman and other 3rd party parts manufacturers actually sell a kit (Isolator Bolt Kits) to fix this problem.

If you follow it step by step, you will eliminate the problem once and for all. Going on 1.5 yrs now.
