Ok so when my car is just idling or even running at any rpm is has this pretty loud sucking noise, i guess, coming from the motor. Its actually almost hard to here the exhaust because the noise is pretty loud. I dont know exactly how to explain it but it almost sounds like theres a vacuum leak or something. I work in a shop but its a lincoln-mercury dealership so not many people know stuff about chevys haha and i figured I might be able to solve the problem easier if i asked around on here. Thanks for any info or advice.
