Hi .

With the air filter box disconnected block the air inlet tube by the MAF sensor so no air can get to the throttler body and the engine should stall , if it just keeps running then you have a manifold gasket air leak ,this is a common issue with this car ,sometime spraying carb cleaner around the manifold will not work .

If the engine stalls then please get back to me for further assistance .
