Hesitation in first gear

Yesterday during launch from 0 mph, I heard a loud pop and my clutch became instantly spongey and I could not shift the vehicle into gear. Over time the clutch, pull, and gears all went back to normal. The only problem I am having now is in first gear and reverse, the car chugs during launch. The only way I can avoid this is by giving an excessive amount of gas. I am going to do a full tune up today; change spark plugs, oil change, swap oil filters and air filters, fuel injector cleaner, all of the small things that could effect the pull. Throughout all of this, the check engine light and/or caution light never came on. What could it be? Do you have any recommendations for what I could do to fix it?
