I have been fighting with mine on the 89 troopper for over a month....have removed the carb cover...cleaned the linkage that goes from the hard wire (from the foot pedal)...and cleaned the foot pedal area with wd40 - up into the actual cable shield itself....NOTHING is working . I wil probably have to replace the cable itself....as where I am in Kenya Africa - TONS OF DUST on game driives and in the city of Nairobi.....
Changing the cable may be your only option......

This is such a broad question! What is it doing to make you ask "how to fix?"
Don't get a pos Isuzu Rodeo
If the bulbs are in good shape but the brake lights dont come on when you step on the pedal then I would say you have a bad stop light switch. It is located on the upper part of the brake pedal. If you look under the dash, just follow the brake pedal and you will see it. It should be an overall easy replacement.
How do i fix the TPS pedal position sensor in a grand prix pontiac 2004.

don't the troopers have a sealed transmission. Like the man said if it ain't broke don't fix it, if you are over on any sort of maintence in the transmission just let sleeping dogs lie, flushing it at this point may just make it worse, of course this suggestion is negated if you are already having problems. But an Isuzu dealership will probably be your only bet
Take it to a service shop.
With torches and soldering sticks.
Check the butterfly in the throttle body on the car. It most likely is gummed up with oil and residue from the PCV system. This will cause the butterfly to stick. Clean this out with some carb cleaner and towels and it should take care of the problem. If that doesn't fix it, try to clean and lubricate the throttle cable.
WD40
you don't, buy a new one
Replace the fuel cap.
