Accelerate

We are going to need more than - just does not sound right.

And Also My Battery Goes From Like 13.9 down to 13.0 and 12.9 as I look at it on the ditital screen is that a problem because I just had the altern radiator and all the gaskets all changed along with a thing called the front motor mount "Dog Bone" because I was leaking oil so they changer all the gaskets and the alternator bause the guy said it wasn't charging the battery after I gave him the car and he said it stalled on him diving it the he had to bring a jumper box then they said it could be the radiator too and I noticed that the needle would go a little above half after the car is warmed up for a lil and so they changed the radiator but the needle still goes a lil above the half way hot and cold point that's the best way I figured to just explain everything if anyone could please help me with advice or tips please very appreciated

Like the acceleration noise I making the right kind of accelerating noise but it doesn't sound like the one it should be making

Almost like it's off or something but it just starting making it after all those new parts were put in
