Its 0degrees here and every time i cold start it,,, turn the keys, in less than half a second the engines moving, a little judder, then vroom ~! Idles fine.

Usually call cars, u can hear the starter motor scank a few times before this get rolling. But with my evo, i barely hear the starter motor.

Is this a problem? Or is the evo ecu programed to dump fuel into the engine when its cold?

 

normality

 

Any explanation for this normality prowakeskayer sir?

 

Oil becomes heavier or the viscosity increases as temperature drops... Thus requiring the engine to use more force, or starting power to turn the motor over. I would recommend using a 0w-30 or 0w-40 motor oil in those low of temps.

 

Thank you BEKevo for the info.
That might just be it. too bad winter is moving on, should have asked this forum earlier. I guess i should be doing oil changes when the seasons turning
