as for rojak prob....
i was facing the same prob oso....
when free gear wif a/c on rolling to red light..engine dies...
FICD edi in....
end up solved with grounding n v/stab.....
as i got a feeling it has somethin to do wif the voltage...
coz everytime when compressor run...engine dies....
even now wif the grounding n v/stab....
the rpm will drop till vibrate quite bad when compressor run....
i'm using 92 SOHC block,60mm tb, 93 4-2-1 extractor....

It could be an almost seized up compressor also, as in an almost kong compressor. there is alot of possibility..

I already have grounding in my engine bay, also I have change the compressor and problem still remain the same. The engine didnt die off but drop to 600rpm which is low and vibrate a lot.

Sound like we may face the same problem even with FICD install.

Re: Aircon idling problem

All sifu-sifu here,

I facing one problem which I have hard time to solve it, can recommend good mechanic very good in 4g9X rojak to check the problem, location is around cheras.

Problem is aircon idling. Start the engine under normal temperature, 1K rpm. switch on aircon drop to 650rpm. the FICD really suck a lot of air from outside but the idling wont increase.

My mechanic already try out

1) 3 set of TB, 50mm 4G91, 54mm 4G93. also check manifold no leaking.

2) install toyota FICD, also change another set but problem is the same.

3) Most of the thing can normal machenic can troubleshoot already done.

4) recently just do complete overhual (problem started before overhual)

5) New MMC timing belt & complete overhual kit, new water pump.


some of my engine spec : =
engine 4G91 (2 years using it) halfcut complete
head, intake & TB 4G93
K & N drop-in
MIVEC extractor
8.5" clutch kit

All sifu-sifu, Please give advise or recommend mechanic for troubleshoot the problem.

thanks!


So ayell sifu, you are very happy with the close ratio gearbox lar.....haha.....

bro,y i didn't meet your problem???u r using SOHC or DOHC
i using 1.8 DOHChead,intake but TB using 6A10,60mm....
cold start RPM @ 1.3K,warm temp @ 1k,air-con on @ 1.2k...last time even hit 1,5-1.8k when air-con on,i take many time to low it down..
did u chk your ECU??
i think 4g91 ECU can ask tune for the idle when air con on...
or maybe your stepping motor damage..DOHC T/B got 2 sensor,using motor to control aircon idle,
if SOHC T/B using screw+sensor to control it,if u r SOHC,normally the screw plastic damage,change it out i think can solve your problem...
i have done many FICD for 4G9x series,actually many of them are not function as well....so...

I am using 1.8 DOHC head, have try many type of 54mm TB, also change sensor b4, still cannot.
Try put in FICD, first one fail so engine die off easily, change second one and the engine wont die off but idling is around 650rpm, when the aircon on the FICD really suck a lot of air into engine, it just cant tune up to 900rpm. no method how I turn the FICD it still stay the same rpm but suck a lot of air.

Now I dont have clue where to troubleshoot......

If your engine idling and press clutch 100% will cause the idling drop mean something to do with your TB. mine didnt have idling drop when pressing clutch while idling(vehicle station).
