ok i have a 94 gsr and whenever i start it, it jumps up to 5000 rpm's like if the throttle is stuck except whenever i look into the throttle body the butterfly is closed. it just started doin it randomly anybody know what the problem might be thanks.

 

do you have a check engine light?? might be the throttle position sensor?? it was causing mine to stick at 2500 at idle for some odd reason.. i denno..

 

thanks you solved the problem
