Help Solve these P1 codes. Guido isa foaming at mouth from FRUSTRATION!
P1776 Ignition Retard Request Duration Fault
 P1777 Ignition Retard Request Circuit Fault Although the car runs perfectly fine, these are 2 persistent codes that can't be erased. The only light on is the tpms inactive symbol because I have on tires w/o sensors. I have no idea what these codes mean or why they're being thrown. I've only had the car 3 months and I'm nervous. I need your help guys. |
