I was about 300 miles from home when I noticed the possibility of a head gasket leak, that's not to say how long it had been leaking prior to this.
I didn't have the money to have it fixed at that time so I drove it home.

I had the heads checked for warping and they both checked out fine. I was also informed that rebuilding the heads would likely cause problems on a motor with so many miles (249,000) so I opted out of the head rebuild.

I never had any problem with this truck the entire 249,000 miles. I have always kept the maintenance up and she has ran fine for years. Now, I am getting 4 codes after head gasket replacement.

Fel-Pro Head Gasket set # HS 9081 PT-1
Replaced all Fuel Injectors: BWD Part # 57792
Replaced Intake Air Temperature Sensor: BWD # WT3050

Now I am getting codes:

P0113: IAT Sensor 1 Circuit High Input

P0133: 02 Sensor CKT Slow Response (Bank 1 Sensor 1)

P0172: System Too Rich (Bank 1)

P0175: System Too Rich (Bank 2

I torqued all bolts and nuts involved in the head gasket replacement to spec per the Hayes Repair Manual.
I made sure all connections were connected before posting this.

My question is, If code P0113 is fixed will the remaining codes possibly go away?

Vehicle: 1997 Ford Ranger 4.0 4x4
