ok guys some day i might get to finally drive my truck, when i start my car it will idle, i think it might be idling kinda high, but thats not my biggest concern, if i give it throttle it just revs up and dont go anywhere, if i pick the back tires off the ground they will spin pretty fast but if i put them back down while spinning they stop and it stays reved up, it is a xxx-nt with a o.s. 18tz, thanx Travis
