Could anyone tell me if there is a cut out on the engine when its idling,if I rev it up, the engine cuts out at 4000rpm is this normal??

Completely Normal. There is a rev limiter built into the PCM.

The limiter is removed if you are rolling at over 15mph.

What do you mean be cut out engines dies or it will not go past 4k. Most bvilles have rpm limiter so it will not go past 4k in idle. It is bad for the motor to rev high when their is no load. You post the same time as did

Thanks Bill that was quick.............ya never did it before and I figured it was to protect the engine or someone like me red lining it.........lol thanks again Bill

Never free rev the motor like that. That'* the worst thing you can do to ANY engine.

In my opinion, the rev limiter should be set no higher than 2,000 RPMs.

Thanks Vital............Ya I was getting a rattle from the exhaust, was under the car and everything is tight so I figure it maybe a loose baffle ,thats when I noticed this when I reved the car up and ya not a goo thing I know

No Master it did'nt die just looped at 4000

Mazee...good chance your rattle is the shield on the cat converter. The welds frequently will break and rattle. If not..kick the cat and see if it'* internal.

When I used to own my 93 I was getting a rattle too. It ended up being the heat shield above the muffler, under the trunk. I screwed it back up and it was good as new. Check that area too.

Ya thanks guys..............I already wired up that dumd bracket on the converter before and held on to all the shields ,it was'nt that so I did hit the converter with a rubber mallot and it is a little quieter but still there
