Hi everyone,
Hoping someone can help me...don't know alot about vehicles. Purchased a 2003 Venture and have had noise problems from day one. Started out with anytime you pushed on the accelerator or decelerated, there would be a high-pitched squealing sound coming from the floor board/engine area. Took it to a dealership, they were ridiculous and said I needed to replace the windshield, that the seal wasn't tight. But noise doesn't happen at cruising speed, just upon pressing the accelerator. Now, the noise happens constantly. Even sitting in the driveway, just turning on the car, you can hear the squealing sound without even pushing the accelerator.
Spoke to another Chevy Tech and he thought it was the mass airflow sensor in the intake manifold - said the new ones made noise when air came in. However, spoke to Chevrolet directly and they said they've never heard anything about it. My husband took out the sensors and the noise remained.
Can't figure it out...sounds like a vacumn hose is loose or a belt is sqealing..it's so loud now the radio doesn't even drown it out. Anyone have any clues as to what it could be or how to fix it?
Thank you.
