hi newbie lang ako dito sa thread na ito, magshare lang po ako. Akala ko ako na ang makaka-experience ng frequent problem sa engine ng avanza coz i converted my avanza sa taxi, naka LPG kit na din sya siguro mga 2.5 years na at meron pa din nakaabang na 2 unit na gagawing taxi. 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....
