Stalling Mazda 323 engine

**ian_rex** · March 24th, 2004 01:46 PM

hi guys. a friend of mine owns a mazda 323 familia 98 model. medyo na nagkakaproblema na siya dahil bukod sa laklak ng gas e kapag nagpepreno e namamatayan pa ng makina. ano kaya ang problema nun?

thanks!

ahh... the ever present idling problem of the mazda familia...

i've used to experience the same problems but was later cured by a fuel pressure regulator. caloyski also suffered the same problem was it magically disappeared one day.

even the service mechanics are at a loss on how to cure this permanently. they can fix this but after a few days it'll come back.

you can try these quick fixes:
- computer reset
- clean the throttle body
- change your spark plugs to cold ones
- tune up

may have something to do rin sa electrical kse pag nag-brake ka, you consume additional electrical load then sabayan mo pa ng pag-on ng aircon/auxiliary fan. i remember before yun friend ko nagpalagay ng relay sa aux fan para ma-minimise yun fluctuation sa power pag nag-on yun aircon.

when you press the brake kasi, the computer will lean out the fuel mixture. kung medyo out of tune na makina mo, that might be sufficient para mamatay yung makina.

try nya muna tuneup. if that doesn't work, adjust niya idle (lalong lalakas yung laklak ng gas though...)

try mo dalhin sa signet sa commonwealth. dun ko pinagawa yung similar prob ko dati e (although balintawak autocenter pa sya nun) at naayos naman. di na bumalik yung problema kahit once o twice a yr lang ako pa change oil/tune up.

**ian_rex** · March 25th, 2004 08:03 AM

ok. i'll have it relayed to my friend. let all modesty aside, barubal kasi gumamit yun e.hehehe. kaya ayun binibigyan sya tuloy ng problema ng auto nya. ika nga "Take of your car, your car will take care of you". by comparison, let me quote sir mazdamazda, mas bata pa ang ride mo kesa dun (kilala mo ito). meron pa ngang nagiging problema yun e, sa electricals naman. yung ribbon cable underneath sa steering column. wala syang busina at the same time yung airbag non-functional na rin. sayang talaga yun. "crush" ko pa naman yung 323 nya.

What are these fixes? How do you do them?

I have the same problem and tried the other fixes, but it didn't work. Sabi ng mechanic me problem pa din sa idle, suku siya.

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.

**mazdamazda** · March 26th, 2004 09:32 AM

ako weird ng timing ko...

pag umaga... ok... pero pag gabi... medyo nag didip ang idling kapag nilagay mo sa neutral ang clutch... then unti unti ulit siyang tataas...

pero not to the point na katulad dati na nanginginig ang makina tapos namamatayan...

quick fix? change your plugs to bkr6e... yung ang cold plugs ng ngk... kasi ang stock is bkr5e...

computer reset? um, tanggalin mo lang ang battery terminals then press the horn then ibalik mo ulit... ayun na yun...

**caloyski5** · March 26th, 2004 02:59 PM

cleaning the throttle body helped solve most of the PTP guys' idling problem..yung sakin weird talaga...im now experiencing it again...labo.. try bringing it to kia commonwealth/prince motors..the service manager there is well-read with the mazda familia

**coiter** · March 26th, 2004 04:05 PM

wierd a. is that prob common with gen2 only? or pati yung gen2.5? akin kasi gen2.5 e. once naayos sya, di na sya bumalik. di ko talaga alam kung anong ginawang ayos dun. oh well, nakatsamba cguro ako. hopefully maayos din sa lahat. good luck!

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.

**Tiny** · March 27th, 2004 01:40 AM

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.

**orly_andico** · March 27th, 2004 03:13 AM

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.

**orly_andico** · March 27th, 2004 03:17 AM

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

**Tiny** · March 27th, 2004 07:32 AM

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,

**orly_andico** · March 27th, 2004 03:33 PM

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.

**jackaroo** · April 4th, 2004 12:06 AM

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.

**Tiny** · April 7th, 2004 01:20 AM

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.

**caloyski5** · April 8th, 2004 08:32 AM

ey tiny, log on to our board para merefer ka namin sa recommended shops...

**speedyfix** · April 9th, 2004 03:07 AM

tiny sounds like a clutch master problem. why not bring it to the shop if you're in the area
