Question

I have a 2001 Lincoln LS 3.9L that is bucking with a code U1027. How can this be fixed? We also have a code P1233

Answer 1

Try fixing the P1233 code first, that problem will set the U1027 code. The problem could be the Inertia fuel shutoff (IFS) switch needs to be reset or Faulty Fuel Pump Driver Module (FPDM).
