500 rpm and shaking

[dieselpowah]

Hi po.
Car is rav 4 2007.
Story goes like this.
Nadrain yung battery ng car. May light ang instruments pero pag turn ng ignition key everything went very dim and nothing happens no click no sound of engine cranking.

So Nagpadeliver ng battery sa motolite.
Nagstart na. However, when we made a full stop at an intersection nag 500rpm and car started shaking. And pag nagmenor sa mga intersection ganun ren nagshake and 500 rpm.

Gonna try resetting ecu (remove terminal for 30mins).

Idle air control valve, yes kaya yan i-DIY kung matyaga kang magbaklas kabit. Check youtube marami kang makikitang tutorial dun with connection sa problem mo. Dun lang din ako natutu 😄 kaya madalas diy na lng ako now

It's possible you just filled up with dirty fuel.

Solid shell vpower lang nilalagay sa car.

Just cleaned the iacv. Pati yung flapping thing. Then ok na. No more low rpm idle.

Thanks sir mantis.

mga sir ito rin problema ko konti lang alam ko sa tungkol sa engine Td27 nissan frontier napalitan ko na yung mga fuel filter, minsan po 500 rpm biglang mag fluctuate sa 1k rpm mayroon bang IAVC yung ride ko saan po yun naka locate

unang una kaya nanginginig rav4 ay dahil mababa rpm (500). pangalawa ang 2007 rav4 ay throttle motor na so walang iac valve. ano ang dahilan at bumaba rpm- ganito yan ng mamatay baterya nawala sa memory ng pcm ang learned throttle position nya kaya ng ma restore ang power nag default siya sa default value which assume nya na bago and malinis ang throttle body (walang compensation sa carbon built up sa throttle). what to do- disconnect battery negative, tanggalin throttle body,give the throlle body a good cleaning esp the plate. pag tapos na reconnect battery, ignition on (engine off) mga 5 sec ign off mga 10 sec (3-4 times). start the engine and it[s done.

also the above procedures ay applicable din sa mga may throttle motor but ingat sa mga ibang car na makukulit na di kaya ng ganyan procedures like chev optra and nissan x-trail
