Dear Nairalanders,

Is there any technical input that can reduce the effect of AC on engine when AC is switched on?
My engine shakes badly when AC is switched on and it wont move well. Toyota Camry 1996 is my car
Helpful comment will be highly appreciated.

I'm not a car expert...but I have a few personal experience..i had a 1998 camry once......that behave exactly like what u described....mechanic checked it and recommended a change in the engine..so I bought another engine and the car was like tokunbo...very cool..so I guess the power of the engine wasn't all that good so it puts too much pressure on the engine whenever AC is on.
Case number 2 I also used a 2004 accord same issue happened...well it wasn't the engine that was old this time but all the engine seats were completely damage..so I Changed 4 engine seats..al vibrations stopped and the car was back to normal

the same thing happen to my Toyota Camry 2007.I use a.c for 8 good years.very chilled a.c before I change engine seat am the problem stop. the a.c put so much pressure on d engine

Most likely: Throttle body dirty / ISC system faulty.
In addition to engine needing tune up or losing compression.

Thanks all.@CoolSegun2002 I will look at the option of engine mounting. @Mementoes I just changed the tps sensor as the rpm was not exceeding 2000 in all gears. I will also try the throttle body cleaning.

Happened with a friend of mine's Camry 1998. Mechanic increased the engine's fire and the problem stopped. So it could be your rpm is low hence putting pressure on the engine when it's working.
