The P0030 abnd P0135 indicate an electrical problem with the bank 1 upstream heated O2 circuit. "Usually" that would be caused by a bad sensor but it could also be a wiring or connection problem. The P1516, P2101 and P2176 are all related to problems with the throttle body and "usually" that would be that it needs replaced, however it could also be an electrical or wiring problem or even a problem with the ecm.
