Would too much timing cause a rattle when you shut off the car?

I thought it was the torque converter becayse the bolts seemed a little loose but its still making the rattle.

Kind of like it wants to keep running. Idle seems a bit off too.

When I had the car programmed last year I had a spun bearing at the time so I don't think it was done accurately.

sounds like a deisel?

It runs fine but when I shut it off it rattles.

Do you have a way to get under the car to tap several areas with a rubber mallet?

Try pulling the coil wire to crank it for a few seconds and see if it will rattle when you stop cranking it to help locate the problem.

When you turn off the ignition, you have only residual fuel in the cylinder (which could fire in the cylinder 1 time possibly). There is no injector pulse or spark possible with the key off (so timing is not a factor), so it is likely something else.
