A dirty carburetor or something is restricting fuel flow. When you hit the gas pedal, the throttle plate opens, allowing a lot of air in, the engine vacuum ...

yes
what you have indicates a faulty brake booster allowing excessive into the manifold and up setting the air/fuel ratio for idle
simple check is to start the engine with the hand brake on
idles ok then put your foot on the brake --problem -replace the booster

Any lights lit on the instrument cluster ? Check engine , yellow wrench symbol ? Your vehicle has electronic throttle control , drive by wire . Stay's running , but if you push the gas pedal nothing happens ?????

unless you want to blow up the intake stop giving it gas before you turn it over what you are doing is dangerous all you are doing is dumping raw unburned gas into the bottom of the intake to the motor, one of these times you go to start it it will do this boom really loud then die, it will lift the whole back end of the vehicle off the ground, then if you try to start it again okay I edited the answer also could be your catalytic convertor plugged is the exhaust coming out good, change the sensors whatever you do stop pumping the gas if it wont start now get in as you need silence so shut the door and the radio off can you hear the fuel pump? it will sound like a huum for a few seconds if you cant there is your problem all I can say is stop pumping the gas as that's why its running bad you are burning out the sensors and all the computer code stuff and wasting expensive gas too. you prolly fouled your plugs as well.

the brake servo needs refitting and ensuring correct torque

This will help.

Thanks.

Head gasket has failed and your engine from what you have described will need to be replaced, the clack and no power indicates that your crank shaft bearing has slipped and your you have low oil pressure now throughout your engine.
Oil pressure is created by the crankshaft bearing and for you to have to push hard on your brake peddle to stop also indicates that your engine is low on vacuum caused by a blown head gasket.
Thank you for using fixya and sorry for the bad news that a new engine is called for to fix this issues.

Is there somthing hitting the gas pedal, like the floor mat? Or maybe something under the dash came loose and is getting caught under the brake pedal and pushing on the gas. Put the shifter in neutral if you get into a situation where going to hit something or someone. The engine has a rev limiter, to prevent it from over reving.

I assume the clutch won't release. Put the trans in neutral and start the engine. Let it get warm. MAKE SURE THERE IS ROOM TO DRIVE THE TRUCK, WITH NOTHING IN THE WAY. Stop the engine, put the trans in first, and start the engine. The truck will jump forward when the engine starts. Get it on a clear road, push the clutch pedal in, and hit the gas. It should come loose in one or two tries.
