Anyone done a smoke test before? Got told at engineering there is a boost leak. Which i doubt. Its more of a turbo whistle imo.
But to triple check, decided to smoke test. Noted the airbox seal leaking.
Curious if others have seen it. Its possible the air filter has aged and isn't providing the sealing force it once did.
Also thought this was an interesting one for future people. Failed smog twice. Which I now believe is a bad O2.
I randomly got this P code only after approx a 40min drive.
Code P0125 indicates "Insufficient Coolant Temperature for Closed Loop Fuel Control,"
Randomly decided to scope the O2 sensor. Dead flat. Before and after trying a spare sensor.
