Sounds like a bad IAC motor, or a vaccuum leak, or low coolant... I would definately start with checking these things first

My 2002 Acura tl revs while in park and in drive, check engine light just turned on as well.

The throttle body and idle air control motor needs a good cleaning. Use brake clean and a toothbrush and clean inside the throttle as best you can. especially the back of the throttle plate and where it sits against the throttle body. Start the car, it will take a second or so. Then rev it up and spray some cleaner in the throttle keeping it running. This usually takes care of the up and down RPM's. Have the codes checked to see what is going on. It could be the idle air control motor. Let me know.

1999 acura tl 3.2 at 3000 rpms it acts like it has a rev limiter. An it wont let it shift until you let off the gas

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Engine stumbles upon starting and when I rev it, it stubles around 5000 RPM. Otherwise drives fine...

How many miles are on the vehicle? When was the last time it had a tune up? It could just need a tune up, or could be a sensor issue. Even dirty fuel injectors could cause this. Once I have more information I can try and help you further although these problems can be tricky.
