As soon as the rpm goes pass 4000 it drops back by itself to about 3500rpm then goes up to 4000, then back, then 4000...on and on as long as I keep the gas peddle steady. This seems very much like there is an RPM limiter that cuts fuel automatically under circumstances. I wonder if there really is such a limiter or the engine has something went wrong. I have never noticed this before, and the car does well on the road with engine going over 5,500rpm with no problems at all.
Thanks for any input!

yes it is a rpm limiter. i have a 1999 with the 3.5 and does the same thing.My lumina also did the same thing. so dont worry there is nothing wrong with your car.
