It is possible the throttle body butterfly is sticky and not opening correctly. To fix it get a throttle body brush($1.99 at the store) and clean the carbon or dirt out of the throttle body. You can get to the butterfly through the air intake. screwdriver removes the hose clamp. Use a degreaser like crc or brake cleaner to clean out the exact area where the butterfly seats and scrub the area with brush. When you start it it will smoke and smell funny for a minute then clear up. This is common on a lot of Fuel injection systems. 5 minute job

How to clean out flooded carburetors?
If it's repeatedly flooding, you need to have the carburetor rebuilt. At the very least the needle and seat are leaking and possibly stuck open. If it runs well most of the time and it just floods occasionally, hold the throttle to the floor and don't let it move while you try to start the engine. When the throttle is part way up, the choke causes a lot of fuel to be drawn in, flooding the engine. When the throttle is all the way down, the choke opens up a bit, letting more air in and cuts back on the fuel. Also, every time you step down on the throttle, you pump a little more fuel into the engine, so if it's flooded, just hold it down and don't let the accellerator pump make it worse.
