2005 Mercury Montego goes into Fail Limp Safe Mode. The electronic throttle body was not the fix this time around. Although the ETB is the fix probably around 70 percent of the time we found out after taking the intake off that the Fuel rail pressure sensor was broken and the Spark Plugs lost its tip along with the Coils fixed the issue. Prior to the fix everytime we stepped hard on the pedal the car would falter into fail limp safe mode. After we replaced the plugs and coil the problem was resolved.so before you go replacing the electromic throttle body all you might need is a full tune up. Remember that we never gotna code for the spark plugs or coil so that is what made this fix so tricky.
