"And this one is just right" ~ Goldilocks
Vacuum leaks are obviously your main issue. While you're in the neighborhood though crimp the thin leads to the coils. The #1 is hard to get to. These routinely get loose and will definitely affect performance. Might as well take that out of the equation. I'd replace the vacuum lines if you have any doubt, new caps, check the MAP sensor, replace the fuel and air filters and change out the gas. With throttle bodies synced I'd expect you'll be fully on your way
