Welcome back. You should know better than to buy a 200 automatic. :)

Pull the codes.

Big job (~8-10 hours), as most of the dash has to come apart.

What does that tell you?

Flush the transmission fluid yearly. Maybe use one of those
powered-flush services offered by transmission places. Some
people will drain what they can (on the V8s, it is about
4 qts), refill, drive, and repeat until you have changed
out 12 qts; not perfect, but better than doing nothing.

It may be the check valve by the fuel pump (in the tank). Bad injectors
can also leak-down.

That sounds like it may be a bad sensor.  Pull the codes. :)
