just bought this supercharged delsol and its a blast to drive and I was going to make this my daily but I have to sell. Car is great mechanically except for one flaw and that is when the car is first turned on it revs from 1k to 2k back and forth for a while, when you drive it for a lil bit it gets less and less and then it stops and the car then idles perfectly fine. idle air control valve? not sure what the exact problem is and I am not sure if the supercharger is the culprit or what. I really want to fix what I can on this car for the next owner. I always get good advice here from members so thanks in advance
