2002 Engine stumble in park

[Cogswell]

Hi All , my 2002 TBird runs flawlessly when driving the car in gear under a load , she also idles & starts flawlessly . When revving the motor in park or neutral it stumbles badly & wont rev past 3000 Rpm ? Has anyone experienced this problem ?
Thanks in advance for any info .

The failure to rev over 3000 rpm is designed into the engine controls. There’s a rev limiter. Does it stumble otherwise?

Yes, my 2002 does that too. Didn't do it until I took it back to the dealer at about a year old for service and they apparently reflashed the engine control module. Has that same 3000rpm rev limiter when in Park or Neutral now.
