1995 mazda protege having problems running during aceleration

Could be dirty throttle body or needs tune up.fuel filter,air filter.

ck fuel pressure ,map maf sensor.timing .

What about new spark plugs and wires?

Could be the Mass Air Flow sensor. But I would check the cold air intake tube first, they are subject to cracking and any hole in it will cause the MAF to give false readings which will trigger the light and cause rough idle, stalling and hesitation.

you got a vacumn leak either a hose or the intake gasket

hi barry i have the same problem did you ever fix yours ?

You may have a vaccume leak

could be the type of plug you are using.I was told only to use ngk plugs.I recently put bosch plugs in my mazda 3 and the check engine light came on and it started missfiring.

The idle on my 2003 Mazda Protege started acting strange one day - it kinda surged forward a little bit. Then the RPM would drop and kept wanting to stall out. It stalled out at a stop sign. The check engine light came on. I drove it immediately to my Goodyear mechanic. It ended up being the Idle Air Control Valve. They had to order the part from Mazda which took 3 days to get there. The whole thing cost $700. Runs great now (again).

Check the air filter hose. My '99 Protege was idling rough and would sometimes shut off. The air filter hose was cracked half way around. I replaced it (easy just loosen two hose clamps and pull out the sensor) and the car is running fine.
