First thing that comes to mind would be a vaccum leak or possibly a bad IAC valve. If you do have a vacuum leak, normally there will also be a check engine light.
Forget the choke...your car does not have one.
Forget the timing... It is not adjustable

Sounds like a vacuum hose leak! If not, might be your throttle position sensor needs replacing.

The most likley cause is a vacuum leak. Itcould be something as simple as a hose or something more costly like an intake gasket.

Take a look under the hood yourself. Look at all the vacuum lines(small hoses) Make sure that they connect on tight at both ends. If one can suck some additional air it will go to feed the motor bypassing your foot control to supply air to the motor which controls the speed of the motor. You may find it under 60 seconds.
