my car is a pos

So as far as plug gap is concerned is it best to have them at .28? The manual says .28 to .31, whats the difference? When I checked them they were all gapped almost exactly to .28
Its a lot better now that the coupling is fix but it still does this weird thing where it kinda stutters at full boost in 4th gear and feels like stuttering when I'm on the highway going about 70 in 4th or 5th. I wish I could explain it better, Cher was with me one night at got to see it first hand...
