im getting a check engine code for the gas cap or a small vaccum leak. I recently changed the gas cap and the intake gaskets upper and lower were just changed. How do i check for a vacuum leak?

With the engine idling, spray starter fluid on all vacuum hoses and connections. When you hit the leak, the starter fluid will be sucked into the leak and then into the intake. You will hear the engine increase in speed. Once you locate the area of the leak, start looking carefully at the vacuum hoses and their connections.
