I went to start my truck today at lunch time and it let outa big bang (back fire). and it didn't start so i turned it over again and the truck start reving all over the place the rpm gauge was just bouncing off the wall and the truck was banging and clinking. i got 3 codes from it but i don't know what they are. the codes are p2108,p2172, and p2106 could anyone tell me what they are and how to fix it thanks.

 

well, i looked on a generic DTC website, cant get the DCX list untill tomorrow when i go to class but anyways:

P2106 is Throttle Actuator Control System - Forced Limited Power
P2108 is Throttle Actuator Control Module Performance
P2172 is Throttle Actuator Control System - Sudden High Airflow Detected

almost sounds like the ETC module is bad, IAC could be bad...we had alot of problems at the dealership with the throttle body having to be replacedalong with the module....sorry couldnt be of more help..

 

that p2172 has something about high airflow/vacuum leak detected (intant accum) so it could be a vacuum leak somewhere im gonna pull it to the dealer. not really looking forward to how they are gonna screw me over this time thanks for the help knowing those codes will save me the diagnostics fee.
