FYI - no carburetor here; you have fuel injection. I know what you are saying, though. I'm wondering if you have a restriction in your exhaust, like with your catalytic converter. I would recommend having your exhaust checked for a restriction. Either this or you could have a big vacuum leak somewhere at the engine - like an intake manifold gasket, or a vacuum line. - DaveJHM
