    check the following:

    1. Electrical (specifically grounding as everyone has mentioned) plus alternator load if it is sufficient.
    2. A/F mix. pag di balanse pumapalya ang idle.
    3. clogged fuel line not enough fuel is being supplied sa carb and too much air is entering the system.
    4. your tensioning pulley baka pigil na ang ikot need to replace bearing (hirap ang makina pag ganito at common ito sa mga old model cars like our corolla)
    5. did you change HT wires when you changed your sparkplugs???
    6. palitan mo na rin yung distributor condenser mo at contact point.

    ganyan din yung corolla ko dati pero after ko ipa-tuneup at palitan ang kelangan palitan ayos na.

    Jim,
    noted lahat sinabi mo, check ko lahat ito pag di pa din nakuha, benta ko na kotse ko, 2 week na akong pinapahirapan.



    2. A/F mix. pag di balanse pumapalya ang idle. ( A/F how can I set this?)

    may screw sa likod ng carb nasa gitna. what you do is to turn your engine on in idle then tighten the screw clockwise. when the engine starts to vibrate badly, loosen it turning counter-clockwise until all bad vibrations are gone. don't overdo yung loosening or else you get bad fuel consumption. this is just a rough setting but it works for me

    you may wanna visit this site http://www.grupotoyota.com.ph/board/ maraming experts sa toyota dito.

    YEp... thats the signs na busted na idle up mechanism mo.. na exprienced ko na to.. I neglect to replace it coz it's still working..pero namamtayan na ako which is WORST. it's really bad coz the vacuum is working On and off... so why not replace it? surplus would be good. 400 pesos ata un nabili ko. I have a mitsu idle up mechanism and it works fine. toyota or mitsu is good.. It is a surplus.

    ganyan talaga idle up nayan minsa ok minsan hindi. ang nakaka asar nito is hindi makita ng mechanic dahil pa minsa minsa lng lumalabas. hehehe.
