Corrola when A/C on Engine output not stable?

Hi,

This issue has been botherd me since I got this 2004 Corrola. When I turen on the A/C, the engine's output seems become not stable. The dangerous situation is when I am tring to park the park, the egine sometime suddenly gives out a strong push and because of the soft brake comes with the Corrola, I will feel that the I may be lossing control over the car and thank god every time I can just stop the car before it hits the wall. Then , here is the question, is it normal that with the A/C turned on, the engine's output can suddenly increase by itself?

Thanks alot. Feng

When the AC is turned on, the engine's output does not suddenly increase by itself. When the AC is on, the AC and engine controls may increase the idle speed. Also, when you are turning the steering wheel at low engine speed, the power steering pump will also send a signal to slightly increase engine speed.

I have seen a similar situation with a 97 Tercel and have always attributed it to the "small" engine and powerful ac. It is because the idle speed is increased automatically when the ac is switched on. If it bothers you, I suggest you turn the ac off while parking :)
