1 make sure that the carb is set to what the manual suggests
2 make sure that the throttle servo is centered
3 check for air leaks

ya you see, i used it before that and it was working fine. Its happended before and i put it away for the day and the next day it was fine. And i think its something with my servo or connections. But i dont know. The throttle servo shakes or moves back and forth really fast. ??? i am really lost and fed up

Check the servo wires to ensure they are not being pinched by the receiver box. Also, check the linkages for binding as well as the throttle trim on your radio. Like stated above, be sure to scope out your carb settings, although you said that it ran fine occasionally....

make sure that the battery pack is fully charged too
servos can act weird if they arent getting the voltage they need

Does it stay that way? i am thinking that you may have accidentally fliped the servo reverse switch on the front of your radio. check that out.
