Why does my car go into limp mode after warming up?
Oil on the ECM plugs can cause a vehicle to repeatedly drop into limp mode a few minutes after warming up while throwing code P1125. This restricts speed to around four miles per hour, leaving drivers uncertain if it is safe to drive to a garage without risking engine damage.
