Wheeler will start and idle but as soon aS YOU TOUCH THROTTLE SHUTS OFF

Odds are your carb needs to be taken apart, cleaned, reassembled and adjusted if needed.

Remove the play in the throttle by loosening the locking pin on the cable, then pull the cable tight to remove the play and refix the locking nut. Once the play is removed adjust the jet so that its steady at idle.

You should have the mass air flow meter checked also have the throttle body checked the idle air control valve is there.

Most low idle speed problems on these engines are due to a faulty idle air control valve but since you state the idle will go up and return to idle then i would say it is working properly i think you have a throttle body coking problem ( dirt and grit accumulates around the butterfly valve in the throttlebody ) to fix this simply remove the fresh air hose from the throttlebody and open the throttle all the way up use a clen rag and wipe clean you may use a solvent such as B12 on the rag but dont use too much

Sorry take it to a dealer who have the right software to diagnose the problem,But first do check the engine breather pipes as i have had similar problems with earlier ford focus where the pipes in the front of the engine split and go soft causing very bad idle/run symtoms

check to see if the choke is stuck or the carb could be dirty (gummed up)

Sounds like the idle jet is clogged

HI disconect battery cable and recconect start engine let it idle for 10 minuts do not touch gas peddle let it relearn idle strategy if this doesent help try cleaning throttle plate by using carb cleaner or the special cleaner whit engine of open throttle spray cleaner using a tooth brush scrub throttle plate till clean

Sounds like it's getting air between the carby and the motor. Check the intake manifold is not leaking
