Check for any engine codes and please post them. What you attempted to do is to "choke" the engine, but instead of stalling the rpm's increased. This indicates a vacuum leak or the IAC motor is stuck in the open position. Remove the IAC ( Idle Air Control) motor and clean any carbon deposits that are on it. Then you will have to test the IAC motor to see if the plunger moves in and out or if it has a dead spot by using a DVOM.
Hook up a fuel pressure tester and check your fuel system, make sure it's got adequate pressure and that the fuel filter isn't blocked, if it is replace as needed.
post back your findings.
