I am trying to replace an accelerator positioning sensor for my '05 GTO; However, the part is unavailable even in aftermarket. It looks like GM had the part outsourced after the failed part was redesigned and whoever was making it simply stopped making it. I bought a pricey Lokar/Williams control and it will not respond and the company told me they only support programming for '06! I'm looking for anyway to get this thing moving again. Even considered getting an 06' ECM programmed but so far no one seems to be confident it will work. So my GTO with only 9000 miles just sits collecting dust.
