Ran out of gas now i have low idle.
So i have a 1989 Jeep cherokee laredo 4.0 I-6. the other day i left my wallet at home was low on gas went back to get it and ran out of gas in my driveway. got a ride put a gallon in and when it fired up it sputered and all but since it was out of gas i figured it would stop a usual. not this time. now it idles at 100rpm almost dies then gets back up to about 800 and kicks back down. runs fine on the freeway or when accelerating. what could be causing this? the wasn't a thing wrong with it until i ran out of gas.
