Could leaving a FC3S TII parked for a month to a month and half do anything to the car?

i'd probably disconnect the battery, so that it does not drain down, but other than that, there should be nothing else to do.

I left my car sit for two months and it drained the batt. Then, about 6 months MORE sitting later my turbo is having some sort of oil leak and my AFM died.

Dont let it sit

I did leave my FC3S TII sitting parked for a month, because I had a leak in heater hose. Once I repaired it, it was driving average, but not as well as it was a month ago. But then about three days later I could floor the pedal and not get a response. Also I have been getting starting issues after leaving it parked for a month, which I didn't have a month ago.
