Guys I got my car 2 months ago hasn’t been running right since misfiring idling at 1500 after idling normally for 30 seconds on start up.. loss of power the code comes up p2279 air leak, done smoke test changed a load of parts throttle body injectors and few other things car still isn’t running right so I tried to reset the ECU but it’s locked…. Is it possible I have a bad map and that’s why the car is not running right at all? Been scratching my head with it for weeks now.
