Trying to figure out why it is idling rough and barely running then stalls, have checked the Crankshaft positioning sensor, nothing helps not throwing codes.
Misery loves company...same car...same exact problem..done most everthing but coil.. starts ok cold but barely runs warm mike
Ck fuel pressure ,map maf sensor.timing .

check the fuel filter air filter and vacuume lines if they all good make sure the spark plugs are making a bright blue spark

Try cleaning the Mass Airflow (MAF) Sensor. My 2002 Protege check engine light came on and it started stalling at stoplights if I didn't keep the engine revved a little. Manager at AutoZone checked the computer code for the light (P0171?), and it said it was running lean. He suggested I try the MAF sensor cleaner they have ($6.99) rather than replacing the 02 sensor, etc.; it made a *significant* difference. (I think I need to do it again to get it totally cleaned out, but the can is for at least 4 cleanings.) The MAF sensor is the large component that air goes through right after the air filter. If you don't have the repair manual for the car (search online for PDF's), you search for the part online to see what it looks like. Mainly, it's a tube about 4" across with some small wire things inside. The cleaner can said it was a 10 minute job; mine took 20 minutes, but only because the tube leading from the MAF sensor to whatever is next (a kind of bent elbow tube, with a couple of accordian-style ripples) tore, and I had to duct-tape that up to seal it. (Still haven't gotten that replaced - found them online for ~$40. Maybe this weekend...)
SOURCE: 2003 Mazda protege had rough idle and wants to stall when I stop.
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).
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?
