Let me start off by saying -- I'm insanely frustrated right now, so any help would be incredible. My car was running perfectly up until the engine decided to disintegrate. My indie mechanic helped me take the engine apart, see if it was salvageable (it wasn't), so over the past six months I got a used/tested N63 and we rebuilt it and replaced everything the N63 is known for breaking.

Finally I got it back. Ran like sh*t. Any medium-acceleration at low speeds lead to a complete loss of power. He explained it was the the throttle body sync and transmission adaptation which would improve over 150 miles. Over the next 350 miles, it did improve, but it's still not incredible. Its smooth and has a lot of power over 55mph, but from a stop (on a cool engine) it will either buck and throw a transmission malfunction, or lose power and potentially also throw a transmission malfunction.

So here they are, all 75 of my fault codes. I'll buy a 6pack for anyone who can explain what the hell is going on. I know it'd take 20 magic wands strapped together to get even close to 0 codes, but I'd at least like to knock out the red ones.

If the engine has to come out, it has to come out. I'm not worried about that, my mechanic had it apart 4 different times. Besides the shrouds, it only takes about an hour. I'm hoping it's something that needs to be recalibrated or a wire that is unplugged. The only thing I've done is try the transmission re-learn.

Again, any ideas, help, direction, or sympathy would be amazing. I just want my fun car back.

How old is your battery? Many codes look like they could be because of a bad battery.
