Hello Scotty! My name is Jesse, and I'm a big fan of the channel.

 I have a 2016 Hyundai elantra GT,  So far it's been pretty good, I put a lot of Commute miles on it. Within the last week there is a new noise that sounds like a screech and comes out of the engine compartment. It only happens when I push the accelerator while I'm driving, its brief, but it happens every time i push the accelerator in motion, kind of like a whistle. I've also checked to see if I could recreate the screeching sound in park. It does make the same sound when I rev in park. If I start the car and drive off I don't hear it. it's only when the car is in motion and I punch The accelerator. What could it be?
