PLS HELP !!!
Dear Jason,
From my experience:Possible cause:-
Condenser Fan Fault.
Try to do the easy part first.Pls check your condenser fan.When ur car is not moving,the condenser is cooled by the fan only.If your fan is working well ( spinning fast) , then aircond gas is cooled by the fan. In this condenser the gas were transfer from gas form to liquid.If the cooling is good enough (100% gas transform to liquid) , then you will see no bubble in the sight glass of the filter. During accelaration, you felt cold because the condenser were cooled by the fan and air.Double cooling.
Compressor
The most important part in the aircond system.Normally when the compressor is fault ,this is because it is to old ( 5 year above) and will loose it task the ability to compress the gas. This faulty can be detected if all the part in the system is working fine and your aircond is still not cold enough. What can you do is go find the mechanic and ask him/her to check the pressure in the system produce by the compressor.The good compressure will show the pressure in between 30-50 psi at idling.If the pressure is 60 psi and going down to 30-50 psi when ramming, then your compressor is still can be use.Ask the mechanic for the detail.
**If all the system is good and you still not satisfy with the coldness, then i suggest you
change the condenser with the large size.. : ) BUT you need to do some modification on it mounting and all the related fitting... if the money is not the object ,then good luck..

Unstable Idling..
During press the clutch pedal and your RPM is down, i suspect your Throttle Body (TB)is damage.THe gear inside the TB is broken, i suspect la. Go servise your TB , mechanic will
change the gearing inside(cost you about + - RM80) and can stand for 6 month before the problem occured again. Try swap TB with your friend if he/she got a spare.
This is common problem for 4G family....:rolleyes: B)
Hope this can solve your problem.....good luck dude...
