2000 Rodeo, after cleaning EGR tube, 2 codes, now 7, help a brother out
 

Hello, so it all started with a EGR and catalytic converter code so I did my research and cleaned out the EGR tube and opened up the manifol manifold and cleaned it and when I went to put it back together it had a double gasket so I had a vacuum leak and finally fixed it only to find out that now I have seven codes which are throttle position sensor and after those and then a misfire any any suggestions?
