Weak idling during cold start

**silver_corolla** · January 11th, 2005 06:14 PM

Hi Guys,

Need your advice sana. Na experience ko kasi lately sa Toyota Corolla 1.6GL ko tuwing malamig ang makina, kapag start ko yung engine namamatay sya kaagad. Bumababa ang rpm/idling nya hanggang sa mamatayan ako. What I did is to start ulit yung engine sabay tapak na lang sa gas para di sya mamatay. I also experienced this kapag na-start ko sya tapos maglo-load ako ng aircon or headlights, the rpm will go down until mag-off sya. Hindi naman ako tinitirik nito basta uminit na makina wala ng problem. During cold start lang talaga.

Ang advice sa akin ng mechanic ko eh yung AUTOMATIC CHOKE sa carburator ko may tama na daw. Kailangan daw palitan na ang AUTOMATIC CHOKE, pero ang problema hindi daw nakakabili ng AUTOMATIC CHOKE lang, buong carburator daw ang bibilhin ko.

Gusto ko sana magpa-second opinion sa ibang mekaniko kung ano ba talaga problema ng carburator ko. Kung may masa-suggest/mare-refer din kayong auto shop/specialist sa CARBURATOR ng Toyota much appreciated.

Thank you very much indeed,
Pete

Pwede kaya ako makabili ng Automatic Choke lang? Kasi nagtanong ako sa Toyota Shaw pwede daw sila umorder ng Automatic Choke lang. Pero ang problema ko kailangan sa kanila mo ipapakabit. Matagal kasi sa casa, pipila ka pa. Wala kayang third party supplier na pwedeng bilhan nito?

HG,

nagpapa-repair ka ba sa Shell Las Pinas beside KFC? Doon kasi naka-based mekaniko ko.

SC: di pre. although I get my gas there regularly. ang mekaniko ko kasi based dun sa shell las pinas - tramo - caa (yung malapit sa southvale).

4A-GE na ang katapat nyan sir...

Hehe joke lang.

What happens if you do a manual choke when the engine is cold?

Silver_Corolla,

I had a 1990 Corolla 1.6GL before (the orig 16 valves). I'm not sure if you have the same car. Anyway, I had a similar problem. When I turn on the aircon, the RPM drops to a very low level and makes the engine vibrate wildly. The culprit was a defective actuator that is responsible for pulling up the idling. I think it's a pneumatic device that works with vacuum/pressure of the hoses connected to the carb. This part costs around 3K+ then in the 95's. I got it from a Banawe shop. forgot which one.

I'm sure the part you are looking for can be found elsewhere aside from the casa. I think one of the big importers of orig toyota parts is Celica Motors at Araneta Ave corner Palanza St Q.C. You might want look them up and give them a call.

sorry for the ignorance ha.. pero i have a question...

sa prob ni silver corolla, does it mean na yung choke valve ng carb niya is always open? After reading wildthing's and yenner's posts, naisip ko, pwedeng tama yung mechanic ni silver pero pwede ding hindi. Hassle kasi kung bumili agad si silver ng bagong carb, eh iba pala ang sira, like what yenners experienced. Eh kung i-try muna kaya ni silver to manually close the choke during cold starting (like what wildthing asked)? Kung ganun pa din, ibig sabihin hindi yung carb ang prob. Whatcha think? May kabuluhan ba pinagsasabi ko o walang kwenta? hahaha :D
