Kailangan na ng cleaning ng Idle air control Valve , Throttle body , Maf sensor kailan huling nalinis ito . Check mo rin iyong mga hose ng vaccum baka may leak.

I have a 96 323 myself and this kind of problem happened before. With my car, the throttle body was dirty (dirt was entering through a crack in the air filter hose). You can also have the MAF sensor checked / cleaned. On a side note, the 323's engine bay is so cramped that having the car registered would mean removing the air filter hose to gain access to the serial number; removing the air filter hose would mean disconnecting the MAF sensor. When I had my car registered one time, the MAF sensor was not reconnected and my car had the same symptoms as yours.

For engine concerns, I always go to Wheels in E.Rodriguez. If someone could verify: the throttle body has to be serviced in a clean environment, one that is provided by casa. I tried to have my car serviced outside, they said that they do not have the equipment nor environment to service the throttle body.
