OBD II is throwing codes 1122 1166 1167 1078

1122 is TPS higher than expected, sunnyside tech is telling me I need a new throttle body, sounds like shite...anyone have a second opinion

1166-1167 promary heated o2 sensor. 75k on the engine, 02 should be replaced anyway. what does "heated" mean, it warms up on its own without exhaust

1078 Intake Mainfold Runner Control (IMRC) System Malfunction (High rpm)
what the hell is this???

why are these cars falling apart at such a young age?

thx in adv!
