YESTERDAY I WAS RUNNING MY CAR RICH BECAUSE IT WAS COLD ND I HAVE A REVO 3.3. I WAS RUNNING RICH BECAUSE OF THE COLD WEATHER AND TODAY I GOT MY CAR OUT ND STARTED HER UP. YESTERDAY IT WAS LIKE 20 f OUT AND TODAY IS LIKE 60 f. AS SOON AS A GAS IT IT WAS GOING LIKE 2 MPH AND THEN I LEANED LIKE 1 1/2 TURNS (NOT ALL AT ONCE OF COAURSE). ITS LEAN NOW BUT NOT SLIGHTY A LITTLE RICH AND IT STILL GOES VERY VERY SLOW....

does anybody know what to do?

thank you

First, are you sure your tuning is right? If so then check for stripped gears. Is your truck rolling smoothly and free? Next step is checking your clutch. Start with the easiest solutions and go from there.
