Hi dude. I also run a j-spec auto and experienced the same problems recently, but I am pretty sure it woz just the fuel that I was running at that time. I made the mistake of putting normal unleaded in resulting in shit performance and low revs. Since then I always use Shell Super plus or BP ultimate and have never had the same problem since.

check your vacuum pipes round the fuel pressure regulater and turbo pressure sensor? any split in these pipes will give you a lumpy idle and engine will run richer.
