mileage is high, 160K
however, last emissions the record shows it was so low, literally close to 0 on almost all tests. this was a huge increase. The throttle something was recently replaced because it was idling high. I am thinking it is just an adjustment, would replacing or rebuilding something in the throttle controls be a likely cause for this?

the car honestly has had near perfect tests in the past, it is boggling my mind
