How to solve problem on 4G93 GDI,lose power went aircon is running,if u turn off the aircon while driving can feel the go fast than before,what could be the problem


I don't think you HAVE a problem. The AC system puts a significant extra load on the engine, and a slight loss of performance is normal.

Why the rpm of toyota corolla 1994 model goes down when aircon is turned on


Because aircon uses a lot of power, it causes the revs to drop and the car to use more fuel. Just a fact of life. If you don't NEED to use the aircon - don't use it. And if you do need to use it, expect expenses to rise.

Hi..my kia avella rpm reaches for about 1200 rpm when I start up in the morning and gradually decreases to about 600 rpm.but it takes 10 mins bfore the rpm goes down.is this normal?m And my engine loses...


Yes, that is normal operation for an engine. It needs to run at higher idle when cold and the computer does that through the temp sender. Make sure it's not excessive due to any vacuum leaks. This and the AC power loss would be exaggerated if the engine is not running correctly.

Aircon


The first thing to check is the system pressures, this will indicate if it low on charge which is thenumber one cause of loss of AC.

Aircon does not engage when turned on


the air cond requires the belt on or the pump cannot rotate as the air cond is belt driven on every auto that i know of. now if the belt is slipping it is a cause of one of two things. belt is stretched or not tensioned properly, or the air cond clutch is froze up. when you turn on with no belt the clutch is engaged and you will not be able to turn pump with ease. Install new belt and have air checked for proper freon fill

Engine heat loss power


Like...needle...haystack.
The second time it happened, did you also have the AC turned on? If so, maybe the AC compressor warmed up and seized up. But I think you would have heard your belt squealing, if that was the case.
If it only happens when the AC is on, at least you have a good indication of what to check or have investigated. Good luck.

Jag X-Type 2.0 V6 Auto (2002). Amber engine icon lit and aircon switches itself on. No loss of power/drives great. Temperature gauge appears all normal. After a while aircon switches itself off again -...


The Amber Engine Icon means the same as a Check Engine Light. Your car's ECM (Computer) has stored a Trouble Code, and you will need a OBD II Reader (On- Board Diagnostic) to get the code so you can diagnose what is wrong with your vehicle. You can go to any AutoZone and they can read the code for you at no charge. You will need to diagnose and fix the problem before the Check Engine Light will turn off.
