For almost 2.5 years na tumatakbong taxi ang avanza 1 pa lang ang na-experience na problem sa engine, kc mostly pangilalim lang, like transmission support, stabilizer link, brakes.

Nagkaroon ako ng problem sa rpm ang avanza, nag-fluctuate (taas-baba, ) ang rpm specially pagbinuksan ang air-con. Na-experience ko ito when it reached odo reading of 100km. Akala ko may problem na ang air-con dahil on-off din sya, pero when I step on the gas lumalaban naman ang makina at parang normal, pero pagpinaandar ko namamatay ang engine. So i research sa net kung pano ma-address ang problem na ito. i found out na kailangan mo ireset ang ECU by disconnection the power supply. What i did, tinanggal ko lang ang battery connections at tinangal ang fuse ng ECU and leave it overnight.

Kinabukasan, after 15 hours I connected the battery and put the fuse in place, then started the engine and do nothing for 10min. Whhaaalaaa! it works! So just by resetting the ECU my rpm fluctuation problem was solve.
So balik normal ang operation ng taxi.

Not until it reached 140km, bumalik uli ang problem and this time i was confident to solve the problem just by resetting the ecu again. But i failed. This time it does not work, so I asked my auto-electrician friend what could be the possible electrical problem, he told me there is nothing wrong with the electrical,.. "baka madumi na ang servo mechanism, kailangan mo na linisin. So I checked the servo and found out madumi na pala maraming carbon na nakakapit, so i cleaned it using a carb cleaner,( i think you may use a gasoline or other solvent para matangal ang carbon). After cleaning and reinstallation--- again another success! may engine goes back to normal.

so guys I am not recommending na gawin nyo din ito,

I just wanna share my experience with my avanza na ginawang taxi. Kung maexperience nyo din ang ganitong problem it may solve your problem or maybe not, better ask the experts sa Toyota service.

Again, i am not recommending any solution here, im just sharing my experience....

Boss, bagong bili lang Avanza ko 1.5G (kakabili lang Sept 1 - pero saw in the stickers na May 2011 pa nadeliver sa casa), medyo napapansin ko rin yan, parang akyat baba ung RPM kahit naka park lang ako with engine and aircon on, not sure kung this is normal though. Feeling ko kasi one reason ito kung bat di ko feel ung tipid sa FC.

Guys pa help naman po, whenever I step my foot on brake may naririnig akong parang lumalagatok sa harapan. Kinakabahan tuloy akong i byahe ng malayo ang zoomy ko. Sinabi ko na to sa SA ko nung nagpa 15K PMS ako, nawala naman ung tunog pero after ilang weeks bumalik ulit. Avanza G 1.5 ung sakin 2010 model nasa 19K na ang odo. Any information is greatly appreciated. Thanks.

Yup normal lang yan, it's the alternator compensating for the electricity needed. Maliit kasi battery ng avanza kaya mas mabilis na ma-drain. Lagyan o yan ng 3SM na MF pa, tagal yang akyat baba niyan. Kaso addt'l cost pa tapos fabrication aksi malaki. hehe

yung tunog po na "tug", hindi po grind na sound. Tingin ko mas manipis ang sound ng grind compare sa lagatok

Manual po ung avanza ko.

may "tug" sounds din sa akin kung minsan,
ang tunog ay galing sa propeller "play"

Pa-check mo cross joint sa propeller, baka may play na.

Hello fellow ACPers!

Need your input. I've been experiencing engine vibration this past few weeks with my avanza usually during startup after several hours of being idle. Dati, pag start, nasa a little over 1,000 rpm siya then slowly bumababa.

Lately, sa startup pa lang, medyo mababa na siya at around 750 rpm, then mag lolower pa siya tas biglang mag vivibrate na. Though several times na nangyayari yan, minsan pa lang naman ako namatayan ng engine and thank God habang naka park pa naman. All of these times off ang aircon and lights.

Diba usually may tumutunog na parang "pitik" or switch na naririnig tapos tataas ang rpm? Diba yan yung thermostat (which activates the fan)? Pag bumababa siya sa 750 rpm, after a short while, pipitik siya then tataas ang rpm pero bigla naman ding bumababa. Talagang unusual ito kasi hindi ito nangyayari dati.

Just last night, bago ako umalis ng bahay, nangyari na yung vibration. Pero pinatakbo ko pa rin. There were times on the road na kahit apakan ko ng full ang gas, wala siyang hatak at di man lang umangat ang rpm. Parang naka neutral akong tumatakbo. Tapos biglang kakagat uli. :o Buti na lang at wala akong kasunod kasi pag andar ko pag green ng traffic light, parang primera lang ang takbo ko at ang rpm ko is about 1000-1250. Natakot tuloy ako at baka biglang tumirik.

For me, top of mind kaagad pag low rpm while stationary is too low idling. Could that be the case?
Ilang araw na rin ang sunud-sunod na pag-ulan dito. Could it be caused by a cold engine? (Temp Gauge indicates otherwise)

Gusto kong dalhin na sa casa kaya lang it's a Sunday. Nagdadalawang isip tuloy akong lumakad with the family at baka biglang magka aberya.

My ride is a 1.5 G Matic acquired Dec 2010. Hope these info can help you tell me the probable causes.

Salamat ng marami!
