Other then running the car I would suggest using the additive you you are storing the car for long period. Being around boats the old fuel does affect the injectors and the big block 8.2 Liter and Mag Engine inherit smooth running issues if not run.
My car has been sitting too long as well. I go out and want to take a spin but too dam hot and I need to get it to Levy to paint noise but too hot to drive and I am re-working now. Already tired of this fricking heat!?! :~(
