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

your clutch shoes could be worn. if you have a racing clutch. the spring could of snapped. if your car has a slipper clutch that could be loose? or it could be a diff problem. as they spin freely when lifted off the ground, but go nowhere when placed on the floor due to weight. it could be a dumb question but do you have it tuned proply. if it is too rich it will be sluggish and not move but when lifted off the ground the wheels will spin as there is no weight. but check the clutch sping/shoes, your slipper clutch and diffs.
