Yesterday i nlticed a slight buzzing sound when i was accelerating. It sounded like it was coming from the driver side top part of the engine. I popped the hood and my erg sensor was melted and he hoses were disconnected. I replaced it and reconnected the hoses. I still makes the noise when i accelerate. When at idle, either in park or when i left off the gas driving, it stops. Any ideas on what could be casuing the noise and what could have cause the erg to melt? It sas melted on the front where the 2 hoses connect. Thanks for the ideas.
