Clean your map sensor. The vortex is great but it has problems when it’s cold. You need to try and start it with little blips on the start button, like 2 or 3 seconds. Let the sensors read the air and fuel. Sometimes you might have to give it a little gas. You could also have a void somewhere and air is getting sucked in somewhere other than the air box. When I tear my air box and throttle body off I put a thin layer of dielectric grease or waterproof grease around the edges to seal and catch dust….also helps slide things together.
check your spark plug too
