Magandang araw mga tsikoteers! Nais ko lang humingi ng konting tulong/kaalaman sa car problem ko.
Car details
Toyota Corona 12r engine
Oil/filter changed
Radiator flushed/drained/refilled with coolant
new oil filter
new fuel filter
new spark plugs
new dist. cap and rotor
new hi tension wires
replaced contact points
new air filter
Heto ang problema ko sa ngayon, very erratic un idle niya, taas-baba un rpm needle kasabay ng nginig ng makina, pulsating un engine speed nya minsan bumababa ng mabilis pero nakaka recover bago mag stall.. Pina check ko sa mekaniko and sabi nya lalagyan nya ng Ignitor(?) (hindi ko alam kung bakit,pagkakaalam ko walang ignitor sasakyan ko) Bakit hindi na lang palitan ignition coil? then sabi nya maaaring brake booster kaya ganon un idle ng car ko.. Baka meron nakaranas ng ganito sa sasakyan ninyo o maaaring magbigay kayo ng idea kung ano ang puwedeng sira ng sasakyan ko.. thanks po... Upload ko isang video to show its rpm, un taas baba ng needle ay ramdam din sa sasakyan.. salamat po...

hunch lang, baka may vacuum leak. check mo vacuum hose, sa may carburettor. baka cracked or may butas. minsan yan ang dahilan ng erratic idling.

November 26th, 2011 02:59 PM #4before jumping into conclusion, it is wise to check the obvious first. check the ignition timing, check the engine vacuum and check your fluids and levels. if you could put the information into numbers, you are sure after confirming with specs , then you will have a proper diagnosis

Check ang terminal ng capacitor sa distributor. Nangyari dati sa old corona wagon ko, maluwag lang ang terminal. Bukod sa carburator ang suspetsa ko ay may air leak or baradong vacuum hose, palitan lahat ng hoses dahil mura lang naman ito.
additional:
Check ang butas sa throat ng carburator (yung kino control ng idle screw) baka may bara. Minsan yung filter dyan sa inlet ng karburador nasisira then ang maliit na wire nasama sa gas eventually nag settle doon sa maliit na butas for idle screw. Pag nakatapak sa gas ok ang andar pero pag bitiwan erratic till engine stop. This happened to my old wagon.

Maraming salamat po sa lahat ng nagbigay ng opinyon! I brought it to a different mechanic kanina, Contact points inside distributor wasnt making full contact lang pala, okay na uli manakbo.. Muntik na palang maloko, yun 1st mechanic na naglagay ng contact points all of a sudden "napadaan" sa bahay ko then recommend na palitan ko ng ignitor and brake booster un car ko dahil sa problem na yan! Buti na lang nag 2nd opinion ako. Salamat!!
