99 scrambler 400 i need help!! spark issiue

runs great at idle but when throttled in forward it does the same as in reverse before pushing overide(if it worked) Put a timing light on and when throttled looses spark and comes back just like the rev limiter in reverse. How can the circuit be bypassed? It is consistant in loosing spark not here and there all the time, no fuel issiue, its fine

It might be the ETC(electronic throttle control) if it has moisture in it it will cause problems like that. If rusted clean it with emory cloth.
