Wont rev up

Hello. It seems your Buick's engine is 'flooded' with gas in one or more cylinders. This will cause the engine to 'race' because of a fire in one or more cylinders. The engine gets to high rpm and stays there; this is not good! Good luck and keep me informed; if you want to.

Yes it is the rpm limiter going in effect.

If you hit the Rev Limiter on a Ford, it will simply bounce the rev back down, to protect the Engine. So, no high Revs. But, you should be able to bring it slowly to a High RPM. That is normal. If there are no Check Engine Light on. You are most likely hitting the rev Limit and need to stop.

It should not be hitting the flywheel. You need a professional to look into this problem with a full function scanner to watch the crank sensor signal in real time.

It is a Governor, it is called the no load rev limiter You need to run a fault code test on the electronic engine control

yes there is a limit if you rev your car there is a point it will hesitate thats the limit

Yes there is a governor which limits the rpm to 2500 rpm. It ha been limited because beyond this rev, the engine gets overheated and if kept running it that condition would slowly but surely damage the engine badly. Once you have reached the limit naturally your cruise control will stop working since its supposed to maintain that speed, which is not allowed by the governor. This governor can be removed but then you will have to risk damaging your engine fatally........................sodeep
