just performed koeo and koer tests need answers
so here's the codes i got out of it:
118: ect sensor voltage to high
121: tp sensor voltage higher or lower than expected or voltage inconsistent with intak air flow
122: tp sensor voltage to low
327: egr voltagr to low (cuz it doesn't have one to plug up)
552: thermactor air bypass solenoid : circuit failure
998: engine control system operating in failure mode and effects management programming strategy
so what's causing all this? especially the last one i'm concerned about....operating in faliure mode.....that just sound bad

miles on your car?
sensors get old man and wear out...
here are some links

121 and 122 are repeated after clearing codes.... replace TPS, and repeat KOEO to confirm they don't show.
327 and 552 will not cause any driveability problems.
998 is a cause of either 118, 121, or 122.
