I just started it today after sitting for about 2yrs. Im in the middle of doing a complete flush of the tranny(redline), rear end(royal purple), and oil change(royal purple). Also had to put a new battery in it. It has been sitting with the same gas in it for 2yrs as well(about 3/4 tank) so im siphoning the gas out and putting some new gas in with a fuel system cleaner. I am very weary of running "fuel system cleaners" but it idels as if it needs it. I have replaced the TPS sensor and tuned it higher and lower but it still has a camed out style idle.
