I've already cleaned the IAC Valve and throttle body + Idle relearn. Still same problems encounter

Based on Obd2 readings Idle was 682rpm, When A/C turned on it goes to 588rpm, then goes back to 657

The Engine and transmission support was already changed last Dec 2022

Everything you typed sounds normal to me.

So, the rpm does not change when the A/C is turned on?

 

[silvergem]

It does a little but settles down. It’s not like an old carbureted engine.

so it will burst for 1 sec and will go back to previous rpm?

Seems my problem is unrelated to IAC

 

[silvergem]

Usually it does. You typed that it does, and I said that sounded normal.

Ive updated my post with obd2 readings

Yeah, totally normal.

The compressor clutch engaging puts a big load on the engine, especially at idle.

Do i need to check this on mechanic? The rpm was short of 45rpm

??

When A/C is turned on, there is a vibration , the engine load increased yet the rpm decreased

Idle 682, ac on 657 that’s only 25 rpm. What’s the problem? it sounds normal.

Vibration, it seems the engine rpm is not enough when the engine load went from 25% to 35%
