It would be good to have the actual trouble code.

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.

SOURCE: CHECK ENGINE CODE P2187 SAYS
i had the same code, p2187. check to the left of the throttle body(side facing the front of the veh.
there are 2 vaccum hoses going into the intake. the larger one on top has a spring clip holding it and if you look under that you'll see a smaller one with a check valve. mine was disconnected. plugs in under the larger one.

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...)
