Alright guys I'm trying to figure out why I failed the test...it says here the o2 sensor failed the test and the reading is as follow'd.
Pollutant - HC GPM
reading - 0.83
Limit - 0.80
Average for passing vehicle - 0.00
Pass/Fail Status - Failed
Technically it makes sense, but I really dont understand it...The people at the shop used a machine to figure this crap. I'm assuming they use a machine everywhere?
