Engine dies when idling

[badkuk]

i'm currently having a problem with my '89 Corolla XL. For about 3 weeks, napapansin kong kumakadyot siya, even while at 1st or 2nd gear. On highways going 60kph and above kumakadyot din, but it seems more prevalent sa primera/segunda.

Last weekend the problem got worse. It didn't used to die while idling, pero ngayon napapansin kong biglang bababa yung RPM, then dies out.
i've tried raising the idle RPM pero namamatay pa rin. Right now i'm thinking that the kadyot is just a symptom of this, hindi lang siya namamatay 'coz i was stepping on the gas.


OK pa naman yung hatak, If anything the response even got better after a visit to the talyer.

Kakareplace lang ng
- sparkplugs
- contact point
- clutch lining(eto ang hula ng mekaniko since kumakadyot pag primera, turns out mali pala. oh well)

so ang suspetsa ng mekaniko is a dirty carb, which may have some credence since all this time, pieces of the rubber hose( connecting the ait filter housing to the front of the car) had been getting sucked into the carb all this time. Some of them have melted onto the air filter
i've already tried cleaning it with a carb cleaner, no improvement.


What other causes could there be, aside from the dirty carb?

baka palitin na yung carb? check also the fuel filter sir

[jodski]

I had that same exact problem sa Mazda ko before.
The cause turned out to be the following
1) Yung maliit na filter sa loob ng carb may bara na nag jelly form kaya i need to press hard on the gas para hindi mamatay.

2) Vaccuum advancer sira na ang diaphram sa loob kaya erratic idling

The fix
For item 1: pinalinis ko carb then dalawang fuel filter na ginamit ko. Before going to fuel pump and before pumunta sa carb

For item 2: Since wala na ako makita na vaccuum advance na pangpalit. Nag re route na lang ng vaccuum hoses and binarahan na lang yung isang port ng advancer. Then tune the carb again

Before you check this route try mo muna mag carb cleaner baka makuha pa

Kakareplace lang ng FF ...but i will try that later. Who know baka madale dun, saves me the trouble of carb cleaning ^_^

+1 on the carb.... try muna linisin.... pag ganun pa din, either replace or overhaul na.

Kakareplace lang ng
- sparkplugs
- contact point


have you checked the distributor cap, ignition rotor and spark plug wires? better yet, replace them if they are over five years old

Another thing that can be done is to do a compression check. If it's suffering from lose compression, root causes may include worn-out piston rings and/or cylinder walls, as well as valve seats not sealing well and/or worn-out valve springs.

bili ka ng isang can carb cleaner .180 lang kuha ko nun hardex ang tatak..
mas maganda kung maibaba ng buo ang carb para malinisan mabuti lahat ng butas.at mahalaga din may pang bomba ka sana air compresor or dalin mo nalang sa vulcanizing shop kung wala kang AC

karaniwan naman problema yan kapag carb type ang tsikot. second opion wala sa timing.

thanks for the replies...

Yung contact point OK naman daw; sparkplugs kakapalit lang a few weeks ago(pero pansin ko parang ang dumi na). fuel filter OK pa naman daw.
i've also tried to clean it with a carb cleaner pero ganun pa din


Will try to replace the FF over the weekend first bago patignan yung carb -- it's never been cleaned since i started driving it, but as much as possible ayaw ko nang pagalawin at baka me iba pang tamaan.

Pwede kayang fuel pump ang me tama?

Fuel pump and fuel ilter nga pa-check mo. Baka yun.

ok sir pacheck ko muna...cheaper solution first ^_^

[shadow]

Bili na bago...[emoji4]

[vinj]

^ bili na ng EFI. Hehe.

Anyway, my thoughts would be the carb should be opened up, cleaned and overhauled if it has never been touched for quite some time. Had a similar issue with our Sentra years ago, after it was stored for a time. Had to replace the fuel, overhaul the carb and tune.

[badkuk]

And the saga continues...

So i had the carb cleaned out...nung pagbukas we did see some gel inside, but not really that much. Unfortunately the problem didn't go away, this time namamatay na siya habang tumatakbo. i had left the engine idle for more than 15 minutes so i doubt if it's just cold start issues.

In summary:

- fuel filter replaced
- recently had the clutch replaced
- carb cleaned(not overhauled)

What other things should i look at? Could it be something with the ignition, e.g. contact point, condenser, etc? Sabi naman ng mekaniko OK pa yung contact point. Madali lang naman palitan yung condenser, but i'd like to ask the resident gurus first.

Sorry sirs walang pera pambili ng bago ^_^

Dalhin mo kay Mando sa A&M kamuning to check the carb.

[jick.cejoco]

Again, check the ignition. Check the output at the spark plug end of the hi tension wires. The spark should be bluish white, if it is somewhat orange, the spark intensity is weak and can not provide sufficient voltage to ignite the air/fuel mixture with increasing heat, pressure and lean air/fuel mixture. Check this first. An evidence of weak spark is carbon fouling of the plugs. Dalhin mo sa tuli na mekaniko o sa trained technician

[rqawayan]

^check the distributor cap and ignition coil...

[badkuk]

Sorry failed to mention: aside from the fuel filterand carb napalitan na rin yung sparkplugs and high tension wires.

I read that if the engine dies suddenly, it's most likely to be caused by something eletrical, not fuel related as it would sputter then die. I am starting to suspect the ingition coil. I've observed ovet the years that

- after parking the car after a long drive, mahirap ipastart uli(although it starts ups eventually)
- i've noticed when starting parang me pause before you hear the engine turning. It's gotten more frequent lately

Also, the chassis around the engine bay seems to get hotter faster then usual.

Find a new mechanic.

[badkuk]

Find a new mechanic.

Will do sir..but is there any way to check the ignition coil on my own?
