Hi..my 2009 1.3 toyota avanza had a idle problem when the a/c turn on.idle goes up and down and click sound on and off of the aircond compressor.normal idle if i turn ac off.what could the problem be.


there is an idle up solenoid on the the carburetor. adjust the idle speed at 800-900rpm. RPM up and down is due to a/c compressor engaging. if the rpm drops too low, a/c compressor disengages. observe your idle speed with engine warmed up, turn on airconditioner and adjust the idle compensating vacuum diaphragm adjustng screw underneath the carburetor to the same rpm when a/c was off. that should correct your rpm problem

Check ALL of your pulleys. Look closely at the tensioner pulleys with the belt off. If you feel any slack at all, replace it soon.

I have a 2002 mitsubishi eclipse rs and the oil pressure light came on. When the car is turned on the rpm become lower to about (650rpm). No oil leaks and level is fine. In any gear the rpm is low and when...


Your problem is not the oil pressure sensor, it's because your idling is going too low. If you raise the RPM slightly the light goes out. 650rpm is a little low. I think your car has an Idle control valve ... or look if it has an Idle position sensor. I suspect you have an issue with that.
Hope this helps.

High --1600 rpm ?? rpm idle


The normal idle speed is below 1,000 rpm...between 800 to 900 rpm. I suspect that the idle-air control motor has seized and can no longer automatically adjust the engine's idle speed. This part is also responsible for slightly increasing idle speed when the airconditioning is switched on to compensate for the added engine load. Some cars even have a "step-up" solenoid to increase idle.

When replacing the idle-air control motor, remember to clean the port that IAC motor goes into; there will be some carbon build-up that may prevent the part's cone-shaped valve from seating properly. A can of intake valve spray helped along with some Q-tips works well.



Hope this helped.

Have a great day !!!

you probably need to check the butterfly. its the compinent that controls how much air goes into the engine if it is weared than in idle state air leaks into the engine sometime more sometimes less and cause fluctuations in rpm

secondly there is a rpm switch which controls the rpm you can replace that switch and check

Idle too high +goes higher when put in gear (manual transmision


IAC valve problem. Nissan has a updated harness (with one way diode inside of the harness) to prevent backfeeding for the IAC valve and a new IAC valve also gets installed. That's where I would look. IAC valve or "idle air control" valve.
