Throttle may be sticking in throttle body or you have a major vacuum leak. Spray throttle body with throttle body cleaner and check all of your vacuum hoses.
thanks ill try that
Also may want to check your ( TBS ) switch. That is your throttle position switch it may not be closing your throttle and may need to be replaced.
It may be not closing your throttle letting it suck in to much air.
