Diagnose & replace all bad COP Ignition Coils --- problem gone

Replace front oxygen sensors on all your vehicles at 100,000 miles
That is required preventative maintenance, unless you don't care about
fuel trim & throttle response

I didn't go into details with the codes-- too much too type

I doubt you can work on it

If you want the long version & do it yourself -- I'll give you that later tonight

Just ask what you want
going to need a good amount of basic vehicle knowledge though

Hows this

There could be many issues. These codes read your engine is running too lean. Check : all your vacuum hoses for leaks, PCV valve and hose, MAF sensor. This may require an experienced technician to figure this out. Hopefully I help'd!!

Ford Explorer 4 0L V6 SOHC P0171 P0174 Lean Codes Common Cause

P0171 indicates a lean condition. The most common cause of this is a defective mass air flow sensor. Also check if any vacuum leaks. P0174 OBD-II Trouble Code

Technical Description

System Too Lean (Bank 2)

What does that mean?

Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust.

Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.

174 system too lean
2195 - 02 ozygen sensor signal stuck lean Bank1 Sensor 1

The 2 front 02 sensors are located on the front of
the exhaust manifold.

this fords have very comun problems with maf sensors geting contaminated, if you have not or can hear any vacium leaks, the problem is goin to be a conataminated mas air flow snsor (maf)
allow the engine to cold down for at least 15minutes and the remove the air filter hosing and inside has to have a sensor, clean the two liitle resistors inside with brake or carburetor cleaner, allow it to dry and reinstall it.
