What happens if you give it a little gas ? Hold the RPM's up , will it keep running then ? How does it Idle , smooth or ruff ? Does the idle seam low ?

Have the timing checked; the idle speed is set too low.

Check for vacuum leaks.

Have someone feather the gas pedal while you listen carefully to the engine. If the leak is bad enough you'll probable hear it.
More than likely, it's either a vacuum hose or the o-rings under the intake manifold.

Hope this helps!

Anytime the check engine light is on, you should check the computer for trouble codes. The codes will point you in the direction of the problem and what to troubleshoot.

If it's running rough, chances are that it's misfiring. If the Check Engine light is flashing/blinking, it is definitely misfiring.
If that's the case, drive it as little as possible... Or straight to the mechanic because the more you drive it while it's misfiring, the higher the chance is of you ruining your catalytic converter.

Hopefully you don"t need gas first in the tank.While driving did your motor seem to ruff suddenly and as you went slower to a stop did you pull over and turn car off? When you turned it on again did it start up really ruff without giving gas.Can be that you need a fuel injector replaced you can not clean it because it also works electronic.Toyota runs better on higher octane period.
