I’ve been having a problem with starting my 03 g35 sedan anytime it’s below 32°F, when I go to start it it just blurbs a few times and dies, followed by light gray smoke, but if it’s brown 32°F and I unplug my MAF sensor, it starts and runs fine, just in limp mode until it warms up, then I can plug the sensor back in and restart the car with no problems. Does anyone have any idea why this would be happening? And why unplugging the MAF sensor fixes it?
