Any fault codes set? (tsrm will tell you how to check this)

I'd suspect possibly a TPS or AFM related code but if it shows a normal condition then the likely culprit is the idle speed control (ISC) valve, testing & cleaning of which is also covered in the tsrm, tsrm in fact is your supra survival guide & should be added to your favourites list immediately

HTH

EDIT-: by the way, the SST (special service tool) referred to in the link I posted is simply a bit of wire you use to bridge the specified connectors...

It's just choking? I presume your BOV is vented to atmosphere? That may be the problem.
