This is what happens when you let cars sit for years. Stuff rots, dries out, shrinks, etc. I feel bad for all these ultra-low mileage cars suffering from "storage rot"
My car had a similar case (parked for ~6 years) but nothing too bad. All fixed now and on the road with 0 problems!
Just wait until you get the thing back on the road, and find that over time from lack of use that all the seals have shrunk and now you're leaking oil/tranny fluid/rear end fluid, the A/C is dry and doesn't work, and on, and on.
First thing I would do before proceeding is change ALL the fluids, flushing where appropriate. I mean ALL of them! Oil and filter, tranny fluid and filter, p/s fluid, brake fluid, coolant, rear end fluid.
If the car had gas in the tank it has probably turned to varnish by now, which means the tank, sock, pump, filter, lines, injectors, and regulator are all gummed up. They need to either be replaced or removed and flushed. Not a fun job!
I believe the TTA injectors are larger than the GN injectors, someone correct me if I am wrong.
It's really hard to say what's wrong with the car without actually seeing it... Does it have a fresh battery?
