I have a 5.9. Can't reset p2149 & p 2607 truck runs good until 200 degrees. Engine light comes on runs on only 3 piston.

Symptoms make sense for these codes. Check grid heater solenoid wiring/connections and clear codes. Check your coolant level also- how quick does it get to 200?

 

Can't clear Codes. Tried the button on dash and tried taking cables off battery. Replaced both the injectors and injector wiring harness. Same problems. Same codes. Can't get code cleared.
