Problem with my Wira 1.6

[bem69]

Hi folks,

I got a problem with my Wira A/B 1.6. See, this car was originally auto, and I just converted it to manual (4G91). Even when it was auto, it had this idling rev problem so I thought it was the auto gearbox. Well, its still there, and it happens more frequently.

Anyhow, the problem comes when I switch on my aircon and I brake the car. It is worst when I brake and corner, as that one usually causes the engine to halt. Before the engine dies, the rpm will act erratically, up and down at the between 0 to 2000 rpm. After that it just dies, unless I switch off the aircon.

The problem became worst recently, when I just installed an Apex'i dual funnel intake filter. But I ran the car for a few days without a filter, and it didn't die as much. Like this, should I just run it without a filter? I used a KNN filter previously, but that got spoilt.

Basically, what I want to do is get rid of the problem once and for all as I don't feel safe driving a car that can die anytime I brake and turn.

So gearheads, please give me any opinion or tips, before I head into a workshop and kena ketuk, and still got the problem.

Thanks in advance.

its ur alternator or ur wiring.it could also be that ur grounding is not done properly.something to do with ur voltage i think.

Check the below part of your throttle body. There should be a soft rubber below it. square size about 1inch by 1inch. If it's melted means your ISC motor is burnt. If its not then try checking your ISC gear inside. If not broken then its time to find a replacement ISC assembly for your engine. Common problem among Mitsu/Proton engines.

haiks. kanina takde problem, apek ada problem?

Apek ni takde problem, keta aku yang problem timing.

Anyway, anyone know why my mounting is so awkward? Aiyo, last time my KNN also spoilt because of this, now my Apex'i also? I have to push it upwards so that the black plastic is resting on the er... hose opening? Before this, the filter element was on the hose opening, and it bent the filter abit.

See how the plastic bit is bent.. is that the air intake?


No idea how to check the throttle body underside though, not quite sure what I'm looking at.
At the moment I have a Votech VS installed. Would installing grounding cables help?
