Check the MAF or clean it, check for any vacuum leaks from the intake plenum - the PCV extension tube is a regular problem, check the voltage range on the TPS if you know how, check the plugs and coils, replace the fuel filter, and if it's idling poorly - replace the IAC.

And what Dan said, ethanol turns into a black gum if the gas has been sitting. I've had to service all my ATV's and small yard equipment because of crappy ethanol.

That's just a start...
