Can a bad ECM cause low idle rmps?
I'm having an issue with my alternator not charging
high enough while it's in gear if I'm stopped it will
drop to 12 volts charging while I drive it'll charge
between 13 and 14.2 volts. I've been having
charging issues for a while used a half-dozen
alternators finally ran a key on power from a new
source to the alternator and I'm not burning up
alternators now. Any ideas?
