seems like it has power and then not as much

This is not a constant issue but every once in a while I will notice she does have the same feel of power like she always has. Is there any one thing to look at particularly? Also, I have noticed my lights flicker ever once in a while and I am thinking I may have a loose ground somewhere. Anyone else have this issue and fix it? Battery voltage is good as well as alternator.:banana::shrug:

Is it warmer outside when the car feels down on power, or after it has been run a bit? Higher IATs might lead to the car pulling timing and making the car feel slower.

Thanks. I will look into that.
