I thought about that TLSheff, and checked them again, and they are in the right spot. The MAF sensor has a little tab that wont allow the TPS plug to go in.
I rechecked everything just now.
It takes the car a few seconds of turning over, to actually start, which it never does.
The first time I start the car, after it has sat for a few minutes, the banging is slow, a few seconds between each BANG.
Now if I shut the car off, and restart it soon, the banging is much faster. It sounds like one individual bang, happening quickly, not multiple bangs all happening at once, if that makes sense.
