Accelerating pedal continues to give gas after i remove my foot from the gas pedal
Is there anything obstructing its return to higher position?
If not, the spring that pulls it back is not working.

not sure if it'd be the same thing but i used to have a 93 thunderbird & it did the same thing. in park the rpms would be SOOOO high & it'd be loud & then in drive it'd hit 50+ with no gas pedal @ all. i found out it was what is called an "idle control valve" i went to autozone, bought it & replaced it & TA-DA!!! back to normal she went. i'd check into that to see if it could be the same thing. good luck

I'd have a fuel pressure test done to be sure, it isn't fuel related again. Takes 5 or 10 minutes so cost should be minimal. The other thing that comes to mind is a plugged exhaust. (catalytic converter) Quite possible on a 10yr.old vehicle.
Check and clean Idle air control valve. Make sure its responding to signal as well. Also make sure ther are no vacuum hoses disconnected. This may not be a "cure" but it's a good place to start.

It sounds like the idle air control valve (IAC) may be stuck with carbon build up. You can ether remove the IAC, or if your lazy like i am, buy two cans of Throttle body cleaner. Just follow the instruction on the can and pay attention to the IAC, try to spray the Throttle body cleaner hose towards the IAC. DO NOT USE CARB CLEANER, it's too corrosive to the gaskets used on throttle body's. If your going to remove the IAC, The idle air control valve is located on the back of the throttle body. It has an oval electrical connector and two torx screws holding it in. Unplug the connector, remove the two screws then lightly tap the body with a soft faced mallet to loosen it from the body. Once you have it out and prior to installing a new valve clean the seat inside the throttle body where the idle control fits. This must be very clean! Installation is in the reverse order. Btw, to save some cash, pull the valve out and clean it, this usually fixes the problem for quite a while. Look for crushed / cut, just any signs of damage to the wire harness to your IAC. After you have cleaned the IAC and still have the problem, you may have a bad IAC and needs to be replaced. Good luck and hope this helps.

Have the idle bypass valve checked, also called idle air control valve.
If that valve is stuck in the closed position, it's not allowing the fuel to bypass the throttle plate to keep it idling, resulting in stalling, but will keep engine running if the pedal is pushed down.
