2000 Yukon hard to start in cold weather
It's throwing po300, po446
First one is random multiple cylinder missfire. The second is a even emission control system vent circuit malfuction.
Anyone know what could cause these. When it's cold you have to crank the crap out of it for a minute or so before it will start. Some times it won't start period.

Is it only when the motor is cold or everytime you try to crank it even after the motor is warmed up? Im tracking down the same issue with mine.........https://www.performancetrucks.net/fo...-crank-523782/
