Hi Kampret
It won't be trrottle body problem... go kick your friend's ass for the fault advice
Did your aircon still running cool?
How does this problem happen? After service your aircon?

 

[pyan14]

engine check normally due to the fault sensor. there are several sensor on your car. try to check with your car workshop.

Hi there...

when you turn on the air con...did the RPM went below then 800 rpm and shoot up again back to normal...?

 

[kampret]

when i drive...it will happen suddenly if i used the aircond...and the rpm become 500..and it will be normal again if i turn off the aircond.it happen to you before?

Try retrieve the error code from the ECU.
If there is no code then please check what type of the ECU you are using (5sp - grey socket, 6sp - white socket).
If it is grey socket then most likely its the ECU problem.

Wong...not because of dirty TB aaaa ? clogged vacuum holes...

Yes a clog TB will cause the idling to drop to 500rpm when turning on the A/C
But it will not cause the check engine light to blink.
So far i can only link the blinking check engine light to ECU problem.
It mean, his car may have more than one problem...

kampret - try to get the error code...

Diagnostic Codes

 

[huakenny]

diagnose it so u can easily know which sensor is giving problem

so u can check the sensor itself, harness,connector, wiring etc.

if sometimes ON sometimes OFF, clean everything and plug it back then reset ecu.

if OFF permanent then solved, if still ON and wiring evetything is fine. sensor itself need replacement

bro ist this method working with toyota wish 05?

this mostly applied tro earlier batch car which OBD socket is not available

for wish, since there is OBDII port available, it much easier if u direct plug in OBDII scanner to pull the code
