2008 Chevy Equinox Weird Rough Idle on Start-Up Issue
I have a 3.4L 2008 Chevy Equinox that runs rough on initial start up. If I rev the car, even only one time, to 3k RPM the idle is fixed. Upon revving the engine, the brake pedal gets softer and I can hear running water just behind the steering wheel (driver left). The car runs great after that. I've installed new spark plugs and spark plug wires recently.
