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?
