I am trying to figure out if I have an ignition or fuel system issue or if my limiter is kicking in prematurely. When I rev my motor in park or in nuetral it's seems like it begins to shut down around 4k rpm. If you mash the throttle and hold it, the motor revs around 4500 but kind of sputters and refuses to go any higher. I could swear I could wind the motor out to 5000 or redline without issue in the past. Do your cars do the same?

Thanks in advance as this is driving me nuts
