Anu kaya possible problem neto? Pag naka idle walang problem pero pag inapakan na acceleration, hanggan 2,500rpm lang at biglang baba taas baba taas wala syang power para mapaandar yung auto, pero pag idling lang ok naman sya, my mga sinok lang before ako na naramdaman pero ngaun nga, ayun, yung rpm ayaw ng tumaas ng 2,500. baba taas baba taas. para bang palayado.Converted na yung servo ko to idle up ng toyota.

Based sa mekaniko na nakausap ko, 100% Fuel line related, either fuel pump, filter, or yung mga lines. Tama po ba?

If yes, pano ko kaya madedetermine kung san exaclty ang nagiging problem ko sa fuel line?

Pano ko malalaman kung fully defective na fuel pump? or filter lang? or hose lang?
How much kaya nagrarange price nila from oem up to replacement?

Baka meron service mechanics na can do a home service, im form novaliches, sa town proper(Bayan). Kindly text me, urgent. 09239269226

adobo,
hehehehehe. this is mostly caused by either fuel volume insufficient or more prevalent the tps (throttle position sensor) problem. the symptom is called "hunting". the pcm is confused which one of the two is lying and which one is telling the truth. the reading from the MAF or airflow sensor or the MAP sensor does not jive with the TPS signal, hence the engine is confused and try to compensate and correct itself. this should illuminate your MIL (malfunction indicator light)
