There should be a sensor that bumps the idle up when you load the engine by turning the air/con on
if this is unservicable the rev,s will stay high when air/con is off

High idle benz 190e


Could be a defect in the ECU. But 1000rpm is not that high my cars normal is 1000rpm. but some older models were about 700rpm
The AC rise is normal. You may want to have a OBD II check by your garage or you can buy a unit to do this. It will scan the sensors fitted for any problems.

My 1996 nissan lec engine shuts down when the aircon is turned on, i already tried adjusting the idle. the aircon functions at high rpm. can you suggest a solution.


Hi,
Check the a/c actuator, round metal with rod at the bottom, vacuum hose at the side. Located beside the carburetor.
When you turn on the A/C it will push the idle up( via vacuum system ). It has an adjuster at the top to set the right rpm of your engine.
Test also the vacuum hoses and A/C vacuum switch, just follow that black 1/4" dia. hose( vacuum hose ) and check the system.
If you have no idea on repairing the vacuums and the actuator, my suggestion would be to bring your car to the nearest A/C technician to have him repair it.
Thanks for asking FixYa!

My car vibrates,but dont when i have the a/c off


this means that your idle when the aircon is off is very low. basically there are 2 adjustments for idle: engine idle and aircon idle. just try to locate this screws in your engine. set the engine idle at 700-800rpm, while the aircon idle at 900-1000rpm.

Hi, I have a 2000 S40 Volvo. Of late it has started to behave abnormally. The engine idle speed is has high as 2000rpm, but it goes down to normal as soon as the aircon is ingaged. I have also noticed that...


yes it sounds like eithor you have a vacuum leak or your idle air control motor is out or going out test the iac motor too see if that the problem with a small jumper cable hope this helps

Car jerks when I stop only when I have air conditioner on


When the aircon is switch on it puts a substantial load to the engine: you need to get your car tuned to take into account the load from the aircon. Most car have a mechanism that increases the idle speed when the aircon is active: if you are unable to get your car tuned yet, try making the engine idle speed slighty faster while you have the aircon turn-on (the ajustment screw should be close to the accelator cable connection at your engine end). Don't make the idle speed too high and check by turning the aircon off and on to assess the best compromise idle speed to stop your car from almost stalling (e.g. jerking).

Good luck!

Engine idling varies depending on light or aircon is on/off


dude its normal for first start or cold start that the idle is ok but it must high than normal... its normal because the engine is warming up it self... when it gets warm, the idle speed will return normal idle... your engine is 1200cc, it has not much HP for a great load... and i know its a carburatored engine and its an old engine, your head lyt and a/c fan and aux fan and all the electrical system on your car, uses the HP of you engine and its a lot of load to the alternator driven by the engine to generate an electricity they need and thats why the engine rpm speed lowering down to dead and its shake. thats why when you use your lyts or all electrical, you engine is weakening... the best remede is adjusting you idle speed... its located behind the carburator.. its a small black knob.. just make a twist each eighter way and you'll find out if your idle rpm speed ts incresing or decresing.. just increase it and try opening your lyts and other electrical, if its still shaking then adjust it a little more

RPM is not stable.


adjust the RPM of the engine when the aircon is off that match the RPM of the engine when the aircon is on but not too much.
