Review on 🔧 Efficient and Reliable: ACDelco 38001 Professional Idler Pulley for Increased Performance by Ines Jones

Your engine sounds like an RC car engine, howls when you accelerate, is it a pulley bearing? I ordered this part to save some money and they sent me a janitor, it was in an AcDelco box. I use doorman parts sometimes but the bearing in it wasn't smooth so I immediately sent it back and bought a new ACDelco. Bearing on the ACDelco turned out to be smoother than I expected. That was great. Do yourself a favor and buy an ACDelco here. The engine began to run smoother and fuel consumption increased.
