Sure, a few...
dirty IAC (search for IAC on this forum)
bad MAF
vacuum leak
exhaust leak
ignition problem (timing, plugs, wires, etc)
fuel problem (filter, pump, injectors, etc)
Basically, anything could be wrong... did you check for codes?

You could search "check for codes" in the V6 forum (click on upper right hand of this screen, there's a search button).
Basically, look at your ALDL connector, below the steering wheel. Remove the rectangular cover. There's two rows of pins there; ignore the bottom row completely. On the UPPER row, look at the RIGHTMOST two pins.
With the car off, put a paperclip or piece of wire in the ALDL so you connect the RIGHTMOST two pins in the UPPER row.
Turn the key from "off" to "run/test lights" position- the position right before you would crank the engine. DO NOT CRANK THE ENGINE!!! You'll see your SES light up, and hear your electric fan come on.
The SES light will start to blink codes at you. It blinks each code 3 times. It always (well, it should always) start with code 12- "no distributor reference pulses". This is normal, because hey, the engine isn't running!
Code 12 is shown like this: Flash, pause, flash flash
An example of code 35 would be flash flash flash, pause, flash flash flash flash flash. Remember each code repeats three times. When there are no more codes, the ECM starts over, and will start flashing code 12 (and the rest of your codes) over again. If you have no codes, all you'll see is code 12.
Turn the key to OFF, and THEN, remove the jumper wire from the ALDL.
This info is also in the "3rd gen FAQ" in the "Miscellaneous" (last) section. Find it thru thirdgen.org's main page.
