IT sounds like there is too much fuel being commanded into the engine. My guess is that if you pulled out the dipstick indicator for the engine oil that the oil will be thin and smelling like raw fuel, possibly the level may be higher as well. Excess fuel can make its way into the engine oil crankcase. Not good. IF so get the oil changed and the problem solved to cause this condition.
I would start by checking the computer for codes that may reveal a direction to go in. Possbly the fuel pressure regulator is allowing too much or the is a vacuum leak that is causing the idle to shoot high.
If you get the codes, post them.
Sometimes a vacuum leak can be uncovered by hearing a hissing or whistling sound in the engine compartment while the motor is running. IT can also be flushed out by spraying carb cleaner at suspected areas and seeing of the cleaner get sucked into the engine and changes the idle when that spot gets hit.
