3500 RPM Rev limiter. Bad sensor?

1992 LX limiter will cut fuel @ 3500 RPM periodically. I searched the forums and am going to look at some sensors and wiring, but I want to see if another driver here has seen this.

This member had a similar problem but i don't know if his got a resolution to it.

PM him and ask maybe....

Thanks, I'll do that.
