Why does my 2006 Infiniti M35X lose throttle?
2006 Infiniti (M35X) was giving code "P2101". Vehicle would lose throttle and stay in idle. Sometimes it would run without any problem, and sometimes it would go into an idle and have no throttle. I replaced the throttle motor with a NEW throttle motor. After replacing the throttle motor the vehicle ran super well. Shortly thereafter, it occurred again...no throttle. Within seconds I started the car and it ran without any problem. I thought the throttle motor had to relearn and adjust. I drove the car about 20 miles and there was no problem. On another driving experience at night, the vehicle again lost its throttle, had no power, and the lights went completely out. Within 3-4 minutes I started the vehicle and it ran as it should. Do you have any idea what may be the problem?
