here.s the problem.when i start my car when its about 40* f it starts goes to 1500 rpm stays there for one second then drops to 900 idle. this then leaves you with a car that barely idles you then have to press on the gas to keep it running for a few minutes. now when i start my import it goes to 1500 and it stays there for a minute then over the next few minutes it slowly goes down till its at idle. by this time its warmed up and ready to go. is there any way i can fool the computor into keeping the idle up till its warmed up. i have taked to other mustangs and they have the same problem. thanks guys for any help.
