Engine sputters and stalls out upon acceleration.... 1994 Mazda protege

SOURCE: engine bogs and stalls

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.

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.

You could have a dirty EGR valve, you can re move it from the manifold and clean it with Throttle body cleaner. Might as well buy two cans, since your cleaning the EGR, might as well clean out the throttle body too.
Spray the throttle body cleaner in to the throttle body with the engine running and try to keep it at 1000 rpm and then to 1500 rpm as you clean out the throttle body and let it idle down for 2 min then turn the engine off. Then turn the engine to the run position for 10 seconds and start and let idle, ro for a test drive and hope that solved the problem, if not there a few more things we can do which will consist for tune up.
Note: Clean the EGR first so you don't burn your self since the engine would still be cool before you clean the Throttle body.
Good luck and keep me posted.

SOURCE: 2001 mazda protege keeps stalling

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?

SOUNDS LIKE MAYBE FUEL FILTER NEEDS REPLACE, AND OR EVEN SPARK PLUGS AND WIRES. A GOOD TUNE UP. IF YOU RUN LOW OCTANE FUEL YOU MAY TRY A CAN OF OCTANE BOOST, OBTAINED THRU THGE LOCAL PARTS STORE, IN WITH THE NEXT FILL UP. IT WOULD PROB BE A GOOD IDEA TO GET SOME INJECTOR CLEANER AND PUT IT IN WITH YOUR GAS TO SEE IF THAT HELPS.

Testimonial: "I put in injector cleaner and gas boost. No help. Will replace fuel filter. Could bad oxygen sensor cause this?"
