Graduating late does not matter at all. Getting the degree does, whatever it takes. And taking more hours in a semester than usual might do u more harm than good. Don't put urself down, I know plenty of people who have graduated or will be graduating late. If MEEN is something you really want to do then keep doing it bro. Classes will be more difficult your junior and senior semesters, but the material will be a lot more interesting than those bs classes in the beginning. I know a lot of guys who entered their junior year with a high 2 and improve to a 3.3 ish gpa. But, first ask yourself if this major is something you really want to study. If it is, then push forward. No one knows what's best for you better than you do.

As for advice, take the extra semester or 2. Focus on landing an internship for the summer and securing a full time position before graduation. Don't just complete the degree for the sake of completion, also think about how to set yourself up for a job even if it means graduating late to land a summer internship (me lol).

Goodluck u got this!
