So i got alot fixed on th 85 shelby, the 13 code it gone, as well as the 24, and it is not runing nearly as rich and it goes down the road nice and spools great.. but after i fire it up and rip it down the road, pull back in my drive way, and as i let it idle it starts to bellow smoke, and it smells like burning oil...but its not smoking during driving or initial start and idle, its after i rip it and let it idle down? any suggestions???
