Toyota Corolla 1.3 2E (Carb) High RPM on Idle (Goes up and down when AC is on)

**crlmgl26** · March 18th, 2019 02:24 PM

Hi Guys, Need ko help nyo about sa issue ko sa car ko regarding High RPM pag naka Idle.
When I start the Vehicle Mamamatay, pressed the gas 3 times then start again mag start sys pero I need to press gas for 10 seconds.
after ma press ng 10 seconds parang galit na galit makina.
I've tried playing the A/F pero when I try to turn the Idle speed screw walang nangyayare.
Tried to play na din yung idle mixture screw hinigpitan ko ng kaunte, RPM goes down pero hirap mag start at pigil ang hatak.
Everytime na bumabyahe ako if naka loose ang Idle speed and Idle mixture screw ang bilis ng rpm ng makina.

Other issue on this is RPM goes high and low when the AC is on.
Carb was just newly overhaul.
Timing was set and tappets were tuned na din.
Toyota Corolla 1999 2e 12 valve
Sparkplug: NGK
Engine Oil: 10w40

Question is: May IAC ba ang ganitong unit? if meron yan ba ang makakasolve ng issue ko? Saan po located?
If hindi po ito ang sagot anu po ang dapat ko gawin?

May solenoid dyan na taga maintain ng idle speed. Baka lumuwag yung wire o sira na. Happened to my carb honda before.

Hi Sir, Na notice ko po iyon before carb overhaul.
Kaya yung mekaniko po is suggesting din na may dapat palitan pero di po ako kuntento sa answers nya.
kaya tumitingin po ako ng possible answers din po with tsikoteers.

Carb problem. I think nakita na ng mekaniko problema and offered solution but you dont like the solution (or maybe mas alam mo problem).

Stating the obvious, may sira pa din kotse mo. Maybe its time to follow the mechanics advise? Ano ba daw papalitan?

Choke Breaker Diaphragm ang sinasabi ng Mechanic.
Di ko sure kung tama diagnostics nya.

How will you be sure? Sino mas madami but experience sa inyo sa carb nung mechanic mo?

A leaky diaphram is possible though.
