my 2001 mazda protege starts hard, idles low and high at various times (never normal) and it acts as though its going to stall at all times. sparks and wires are changed no help, changed air filter no help. any idea on what to do?

I had the same problem and found that the air admission tube was badly cracked.
Since this let air enter the engine downstream of the mass airflow sensor it is not measured so the engine ECU don't send the proper amount of fuel to provide the right air/fuel mixture. At higher RPM, the vacuum in the tube is enough to close the crack and hide the problem.
I temporarly repaired it with duct tape until I get the part.

removing a gearbox is not a thumbs up job for the average person,their is no adjustment ,if its slipping then renew the clutch ,most hydraulic systems are self adjusting .Trust me even after 40yrs being a mechanic i still hate doing clutches

Check the air inlet boot going from the air filter to the intake for rips or holes. If rips exist, this would allow air to bypass the filter and mass air flow sensor and will lead to a check engine light appearing. The code would read "too lean, bank 1." If this problem is allowed to continue for long periods of time, the EGR ports will have to be cleaned out and maybe even the intake.
