Rev limiter on 94' Pontiac Bonneville?

Question

My 94' bonneville never goes above 4,000 RPM's when in park or neutral. As soon as it reaches 4,000 RPM's it bounces between 3,800 RPM's and 4,000 RPM's. Why? Is there a way to disconnect it?

Answer 1

It's a safety feature. Free revving an engine, as odd as it may sound, is very hard on the parts. Disable it and you'll lose an engine quick.

Answer 2

I am guessin it is a V6. The rev limiter is there so you won't blow up the engine. If you run it unloaded over 4 then you risk letting a lot of bolts out of the tailpipe.
