Stalling Mazda 323 engine

**orly_andico** · March 26th, 2004 04:06 PM

Work around namin ng mechanic (very nice person) ni speedyfix is to make the idle more aggressive (1k). Although 1 thousand petots/ 280+km per week gastos ko sa gas.

holy crap.. 1000 petot = 42.5L sa old price ng shell velocity (23.5/L) -- pera tumaas na daw by 0.60. assuming yung 280+ km mo is 290 km, 290 km / 42.5L = 6.8 km/L yikes. maybe it's worth trying to fix the problem.

some other things i can think of: in addition to yung sinabi ni caloyski na clean the TB, try also cleaning the IAC valve, and the MAF.

What is "cleaning the IAC valve, and the MAF"?

Wow I'm impressed with the computation for the milage. My fuel consumption is around 41/42+ liters!

Sad thing is I just changed sparkplugs (Bosch Ytrium) before I read this thread.

tiny,
sabi mo 1000 petot eh. 1000 petot / 23.5 petot per liter = 42.5 liters.

the IAC valve is the Idle Air Control valve. it's supposed to control the idle when the A/C, etc. goes on. when it gets dirty, this causes erratic idle.

the MAF is the Mass Airflow Sensor. it measures the amount of air na hinihigop ng engine. when this gets dirty, it causes weird acceleration problems. all of these cleaning, kaya gawin ng suking mazda mechanic (sa mga Ford casa...) or sa Kontact-Point sa Banawe.

isa pa pala mister tiny,

BOSCH IS NOT GOOD FOR MAZDA ENGINES

maraming thread about that sa probetalk forums (the ford probe GT is basically a mazda 626). for some reason, mazda's hate bosch plugs, the temperature is too different.

you should use, and only use, NGK or Nippondenso plugs. these are the OEM plugs for mazda.

sayang.. mahal pa naman yata yang bosch plugs mo! :P

I'll ask the mechanic to take a look at those things (Mass Airflow Sensor and Idle Air Control electrical parts kaya to?)

Ytrium cost me about 85php per plug. Hindi naman sobrang expensive like the Iridium tech other sparkplugs use.

Regards,

MAF is electrical, it's on the air box. The IAC is a mechanical/electric component, it's near the throttle body, it's analogous to the "idle servo" on Mitsu cars.

If the TPS- throttle positioning sensor- was reset then could also cause erratic idle. Have the mechanic check the setting or compare with another 323 engine's setting.

More troubles for me. :dead:

Amoy sunog (burnt rubber) ang whatever and if the clutch is stepped on instant drop yung rpm to about 400 sabay nginig!

Waaahhhh... Taking it to a shop. Holy week pa naman.
