Joined forum because experiencing some starting and drivability issues. Low running voltage was cured with a Mechman 170 amp alternator. Car very hard to start, sometimes will crank and refuse to start. Off idle bog, feels like it wants to stall, sometimes does. No fault codes. Only four test drives so far, not running any better. Will check if enough voltage going to white wire next.
