A "Check gauges" light turns on randomly for a few seconds then turns off, and 20mins later it's on. When I turned on my truck in the afternoon, it sounded kinda funny like a air escape, so I turned off the truck and went to go open my fuel knob, as soon as I turned it, air escaped as if it were holding pressure. What is it? Or what would it be?

In many cases, excessive vacuum pressure that is released from the fuel cell when you open the fuel cap is caused by a malfunction of the EVAP vent solenoid. This component is designed to relieve pressure inside the fuel tank but also ensure that harmful gases are filtered through a EVAP tank before being released to the atmosphere. When the EVAP system is faulty, it can cause the check engine light to illuminate quickly or stay on for extended periods; as well as negatively impact engine performance. The best way to know exactly what parts are causing your troubles is to contact a local mechanic and have them complete a check engine light inspection.
