1998 F-150

My Ford truck recently overheated. That was fixed by replacing the water pump. Since then the OBD scan indicates the EGR flow is insufficient. It seems to run rough. Is this a related issue with overheating? Would replacing the EGR be indicated?

  1. Not related to overheating.

    You will want to start with cleaning or making sure the exhaust gas feed back hoses are clear. Most cases I just replace the EGR, pressure feedback sensor and vacuum regulator, clean the hoses and that fixes the code.
