So I have this weird intermittent where at start up sometimes the stang is really loud an others it's very quiet what would cause this??
It does it in the morning 60deg. Or it does it in afternoon 80deg. It's random I replaced my battery last oct. an new alt. since feb.(2013)Ok, does this happening correspond with outside temperature? As in does it do the higher initial idle when its cooler out or on warmer days too?
