HI all,
Hey can anyone help with these codes? Here is what I downloaded on my odb2 scanner.

CEL has been on for a while. I erased and started over. Drove (cel came back on first day) for a while (about a week) then run scan. Here is what I found:

Year: 1996
Manufacturer: Ford
Make: Ford
Model: F150
Engine Type: L6, 4.9L (300 CID)
Transmission: Automatic
Trim Level: XL; Special; XLT; Eddie Bauer
Mileage: 184000



=== Stored Error Code(s) ===
Error Code: P0171
Possible Causes:

Error Code: P0443
Possible Causes:

Error Code: P0174
Possible Causes:



Freeze Frame Information:
1. DTC for which Freeze Frame was Stored - P0171.
2. Fuel System 1 Status - Closed Loop.
3. Fuel System 2 Status - Not Supported.
4. Calculated LOAD Value - 61.96 %.
5. Engine Coolant Temp - 188.60 °F.
6. Short Term Fuel Trim - Bank 1 - 8.59 %.
7. Long Term Fuel Trim - Bank 1 - 25.00 %.
8. Short Term Fuel Trim - Bank 2 - 0.78 %.
9. Long Term Fuel Trim - Bank 2 - 25.00 %.
10. Engine RPM - 1,729.50 Rpm.
11. Vehicle Speed Sensor - 50.33 Mph.

I know these can run into a bunch of problems or could be just one thing making it all happen.
Truck runs good drives good, however I dont want to run the gammet of spending countless dollars chasing the problem if I can spend once and have the problem fixed.

Any and all help is very much appreciated!!

Fuel Injection Technical Library » How To Run a Self-Test This is a code place look at the bottom of page and it will give you links to codes hope this helps.

 

This is OBD1 stuff, the OP seems to have OBD2 somehow.

A Google of P0171 says the left bank is running too lean.

P0174 is the other bank.

P0443 is the canister purge valve circuit.

 

P0171 and P0174 indicate the truck is running lean as noted before. Any vacuum leak or exhaust leak(s) before the O2 sensors can trigger either code. I suspect a vacuum leak problem, but thought I would toss in another common cause. Also add in low fuel pressure as another cause of a lean code.
