Check Engine Light

[FOP23]

Had Pep Boys run Diagnostic check, they indicated that Bank 1 was too rich, and Bank 2 was too lean. Recommended I take to dealer for repair. You guys have an idea what I'm looking at from repair and cost stand point.

Can't answer that until the causes of the codes are found. Could be something simple that is cheap to fix or could be an expensive broken part.
What were the codes that popped up?

Year and mileage of the truck would be helpful as well.

Any word on the actual codes being thrown?

I have a very strong feeling that the crowd here will be able to give you a much more definitive answer as to what needs to be done...

Codes are as follows:

P1000
P0172

Codes are as follows:

P1000
P0172

The P1000 just means that the codes were reset. It will go away after you drive it. Standard for Fords to toss that code.

Here is a good place to look at the P0172 code. OBD-II Trouble Code: P0172 System Too Rich (Bank 1)
