I have the same problem mga bro. I drive nissan sentra 2007 model. Pag on nang Aircon may squeaking sound pero mahina lng. Same din kaya toh nang issue? Wala sa makina yung tunog e.
depends saan nangagaling..... most people would say sa aircon, pero hindi pala. much better if you can still isolate where the sound is coming from.

Puwede i try, 1. Palit air filter 2. Linis throttle body 3. Linis MAF sensor 4. Check spark...
high idle RPM at engine start
