15' BRZ M/T - Cold start misfire
Hello,
Since the recent weather change here in BC (Canada) I notice when I cold start my car after a night (under ground garage... 5*C -ish). Clutch in, start the car, after about 3 seconds I get 2 pops from the engine bay on the passenger side, rpms dip from 1500 to about 1200. After which the car runs and idles fine. Should I be concerned? thoughts? suggestions? |

Its normal. It is the ECU putting more fuel in during combustion so that it continues into the exhaust and warms up the cats.
