Clean throttle body + do tuning, you have a bad idling there. Around RM70.

I think all old wira have that same problem.
I remember going to a shop where they strap something to my valve which can auto boost the valve flow and control the flow rate when your air con kicks in.
Regardin the name of that piece of thing i dont remember.
Cleaning throttle body and tuning is neccessary but it wont last long.
The place where i got it fix call Rascar auto network at Damansara.
0378065416.
If u manage to find it at other car workshop shud be cool but if your workshop technician tells u to change throttle body beware its a con.

In a carbie, it means the FICD is dead. But in an EFI, the FICD is optional, non existent in most cases. It can be added, but doesn't solve the underlying problem.
Try cleaning the throttle body 1st - this can be easily done with a can of throttle body cleaner available @ Brother's. Then replace the spark plugs as they get quite soiled after that.
If that doesn't suffice, adjust the idling (via the idling screw located somewhere close to the throttle opening) until you get a stable idle while the AC is on & off.

I'm not too familiar with the technicalities of the EFI system as I'm a carbie user tongue.gif But the principles are similar just as our engines are smile.gif

You can try adjusting the idling with a philips screwdriver and see first

My case is similiar to his and to be precise its the same. Most wira have that problem especially if it's an old model. When u ignite the engine , it will be very stable. But when u switch on the air con , the car will start jerking. I've tried to resolve this problem in many workshop in sunway and some told me to change the throttle body to a new one lol. Well tuning and changing spark plug wont work for sure. I'm not an expert in car though , but i've gone through alot of nightmare repairing till i know what's best to resolve TS's problem. If u tune ur old wira , the same dumb problem wont be solve. Dont believe ? ignite ur engine , switch on your air con ,make sure dont change gear , acelerate abit and immediately stop acelerating. U will find your engine dead. I believe it shud be what Goldenhawk mention as the FICD. Most car workshop doesnt recommend this because they want u to visit their shop frequently. My car undergo one last final services adding that piece of gadget with abit of tuning and the car doesnt jerks anymore when i switch on the air con.

That's quite normal actually. Just means your throttle body not at it's peak. Cleaning it will help. If you have cash to spare, take the injectors through a sonic bath.

Which part is the "throttle body" most are saying in a fuel injection car? On normally asp. car the 'Air-convalve' has 2 small rubber hoses. Look around the engine bay nearest to the wind screen and see if any hose, or pipe end is loose or not connected.

Depends on what type of cleaning you're doing.
The usual would be to remove your air-box connection and empty a can of throttle body cleaner spray into it. Make sure you get the nooks & crannies.
Anything more than that, take it to the mechanic if you're not confident...

i had experienced the same thing b4.. but my mechanic told me that there is an electronic device spoil, so need to change 1.. cost me RM15 only.. everything running smooth now..

he told me tat as the compressor of air-cond start tend to consume the engine force, so the electronic device is used to adjust back the carburetor to desire idle..

the thing is tiny with 2 holes which 1 of them connected to the carb. with a tiny pipe..

but for fuel injection type i dunno got such things or not hmm.gif

easy way, go Brother's buy a can/bottle of throttle body cleaner... pour it into ur fuel tank and drive like normal... the solution will help clean the throttle body as it passes through it...
hard way, send to mechanic and have ur TB removed to be cleaned throughly... this is the most effective way, but cost a little bit more as well...

noler... this FICD dun exist in carburetor cars... carburetor engines using a different type of FICD, depending on the car manufacturer....

FICD exist in all cars... but it comes in all shape and sizes... most FICD are not adjustable... but this one (toyota FICD) is adjustable... means we can control engine idle rpm via it... icon_rolleyes.gif

i dunnoe this will help or not..
since u mention once aircond on ..

then u check ur aircon compresor izit starts to jam already or not.. if tb not the answer , then might b ur aircon compressor start to jam d..
there is many possibilities around.. u just have to take notes of which part might giving u the problem oni ...

to check if ur aircon compressor is working all rite just start ur engine , then search for the aircon compressor , look at the aircon belt that connect to the engine .. check if the belt is running smoothly or not.. if fast n slow n fast n slow... means ur compressor start to jam d..

if compressor start to jam, will it produce any sound such as damaged bearing and so on??... will it load down the engine power alot even while driving??... i'm facing this problem, a/c compressor loading down my engine power alot... i went to check but the mechanic said my compressor still works fine.... i'm now still blur what actually went wrong... or mayb less pressure in the fluid running in the compressor to condensor??..

sorry to hijack thread. but these past 2 months i've did a few services to my car as well.

1)cleaning throttle body.
2) change spark plugs
3)change the exhaust middle box?
4) change car battery.
5) normal car servicing.

there is one problem, whenever the car is idle, esp stopping during traffic lights, the car will just like jerk a bit. the feeling sumthing like the exhaust tersumbat and letting out air. how to describe it, ermm, imagine ur shooting peas with a straw, sumthing like tht. my suspicion would be the exhaust at the muffler tip. coz the part already got holes dy, doh.gif. anyways, what other problems could it be?

Dude, what are you driving? Lambo? Porsche?

If it's a carbie, get it re-tuned 1st. Might be flooding the intakes.
If it's an EFI... unsure.gif

Last time i drive a charade aura which uses carburator.
The engine sometimes will jerk even when i accelerate.
Went to service center to change plugs, clean carburator, etc. Waste so much money and in the end, they found out that its my contact point problem.
Need to change contact point as its already worn out.
Contact point is the devide connected to the distributor one i think.
Could it be same case?

how much to clean injector and where?

QUOTE(GoldenHawk @ Nov 14 2007, 09:46 AM)
Depends on what type of cleaning you're doing.
The usual would be to remove your air-box connection and empty a can of throttle body cleaner spray into it. Make sure you get the nooks & crannies.
Anything more than that, take it to the mechanic if you're not confident...

how much if take out the TB and clean throughly?

noler... this FICD dun exist in carburetor cars... carburetor engines using a different type of FICD, depending on the car manufacturer....

FICD exist in all cars... but it comes in all shape and sizes... most FICD are not adjustable... but this one (toyota FICD) is adjustable... means we can control engine idle rpm via it... icon_rolleyes.gif

question. with this toyota FICD i can control the RPM when aircon compressor kicks in right? so assuming if my myvi is idling higher than normal, i can use this FICD to replace the original one and tune it so that its lower? correct me if i am wrong.

thanks catacombs. but if ECU tuning means i need to get a piggyback, right? since AFAIK nobody can tune the perodua ECU.

first and foremost, ts punya car is an efi engine which should be continuously self regulating. if the revs drop that low then it means that something is not working properly

try check ing the throttle body and f that is ok then check the mass airflow sensor.

FICD is not an aftermarket product... it is installed by car manufacturer... the one i'm previously using is from toyota... this FICD has a knob which controls how much air to bleed in/out when it triggers by the aircond compressor signal.... hence, u can alter the idle rpm easily....

my old iswara has some problems like described, but only in the morning...tried cleaning the caburator,but it only helps a while before the problem resurface. Someone suggested that the auto choke might be dead? ..is there such issue?
