MAF will cause this issue. You can try cleaning them, but Toyota does not recommend it. Also, if you do try to clean the MAF, the red bulb is not the wire to clean (That is the Intake Air Temperature sensor (IAT). The part that needs sprayed is the wire down in the middle.

Also The issue with the leaking air on the intake manifold gasket was for 2003+ Corollas when they changed to a plastic intake and the gaskets were plastic/rubber. The 1998-2002 intakes were a fairly stout aluminum and the gaskets were metal.

Good luck

Thanks... I already cleaned the maf. And i did clean the correct area, ordered a new one but it was defective, figures,..When i pulled off the intake manifold it looked good but replaced the gasket anyways, it was the aluminum manifold. Waiting for the replacement maf then i will update..
