Problem with b14 adivice needed.

Car is a b14 with ga15 engine,sometimes when I remote start my car at morning it sounds kind of sputtering with black smoke coming out the exhaust and the smoke is seriously unbearable and burns nose,but as I tip the gas pedal,the car idles up and the black smoking stops.Car was recently tuned up,oil,plugs,gas filter,oil filter,injectors,throttle body.

Do you drive at a slow speed by chance? or you give your car an occasional blow out?

Car does get run hard at times

more than likely, the suspect is the airflow sensor and since its integrated into the throttle body that means more than likely it will have to be changed. In my experience with ga15 and black smoking the more common suspects are throttle body and ecu.

Thanks krisjoseph_2000,I was really told that the air flow sensor needed to be changed but I wasn't sure,I'll change it and see how it goes.
