Ok, installed my jrsc this weekend, its just the stock setup, with the black box. Got everything hooked up, started it up and if idles like a top fuel dragstar. Then the rpm's shot up to 4k, so I shut it off, started it back up, rpms shot up, then back down then sat there and reved by itself. When it does attempt to idle it, feels like it is missing, and the check engine light is on. I backed it out of the garage, and I have no BRAKES! I have the booster cable hooked up. As you can see I need some help here. Thanks
