my car used to be really zippy and now when i drive it almost feels like i left my parking brake on. thats the best way to decribe it. so i started unplugging wires to see if anything changes and there is one clip in the back that plugs into something right by the throttle stuff and there is one that plugs into this pop can sized little cylinder thing right out front on top. if i unplug both of those at the same time it runs a little bit better. i need help! thanks.
