Hey everyone i went from a ngc3 pcm to a ngc4 in my 1973 Dodge Challenger with a 6.1 545rfe combo . I got everything in order except it has a cold start syndrome all the time. I understand its ok when cold it goes to about 1400 ish rpm and gradually comes down to idle within a 2 min or so . But its annoying that it does it all the time , even when its warm . I thought they had a slight idle and came down to idle right away when warm . Is there anyway to fix this ?
Thanks guys ! You all have been super helpful ...
