2009 Corolla S AND general question.?
I've most recently been noticing a slight squealing noise when on and off the accelerator, as in pressing the gas a bit and letting off. It's only when pressing the gas a bit, and around 2,500 to 3,500 rpm's do I notice it. Would you be concerned? It's very slight, the average person might not even notice it. I have reason to believe it to be related to the belt drive pulley or pulleys, maybe even a tensioning issue. I'm contemplating coating a few areas with some WD40... Thoughts...
