That exhaust is terrible!!!! Fix asap!!!!

But if your tach is bouncing like that, definitely a vacuum leak or your idle air control valve is broken. Try that and see what happens. As for the brake light, I couldn't say. But alot of shops nowadays do free brake inspections; I personally go to Goodyear they always give it to me straight.

is this to fix the vacum leak??

you can try spraying carb cleaner on the vacumn lines to see if it "boggs down" ... or visually inspect to see if any are off or dry rotted

clean the iacv, there is a DIY sticky look at that.
look for vacuum leaks
also look at your fitv - another DIY sticky
basically just go to this thread

A stutter:

Can be caused by - A faulty o2 sensor, check to make sure it's working.

Spark plug wires arcing out.

Spark plugs are to cold causing fouling, run a hotter plug with a smaller gap, I preffer .017-.026 depending on upgrades.

A faulty injector not pulsing.

a iacv will cause more of a hesitation and idle surge.

coolant in the combustion chamber, the same goes for oil, yet your plugs will tell you if thats happening.

Water in your gas.

A dirty fuel filter

The 2nd and the 3rd videos, are those when you put your foot on the pedal to keep it from shutting off or is that how your car is without the foot on the pedal?
Check the sticky throttle and cable.
