when i go to rev the engine in neutral or in park it seems like it is limited at about 4k rpm, is that true or is ther something wrong with my motor? also, if it is limited, is there a way to remove that limiting? thanks

 

o i forgot to state this, this is on a 2001 grand prix gt

 

Your car will have a rev limit at approx 3800rpm. This can be removed quite simply by changing your pcm with an aftermarket one. PM me if you would like more info on this, or check out the site on my sig as it has all of the information listed there that you will need. I am also there under the same name if you would like to PM me.
