Hi Guys - I have a 2007 SC 5spd with 218k miles. Yesterday all of a sudden it is losing power and there is a sucking air noise from under the hood when I try to accelerate, however there is no power. Nothing visibly wrong. I have not had a chance to further investigate but it will start and idle with no issues and run for a while until it starts acting up again. I checked the air filter and it is not clogged.
