Aftermarket Throttle Cable?
i'm using a lokar and have never had an issue like that because they're strong as hell and i really don't believe it's even possible with the little bit of force it takes to overcome the spring pressure of a throttle blade!
i would check and make sure your set screws are tight before anything. then double check your length and be sure it's got NO slack in it when the throttle blade is closed. and last be sure your throttle stop is not bent or anything.
good luck!
