I recently failed the Colorado Emission test due to High HC. Replaced Plugs, Oil, Cleaned all filters, filled with 93 octane gas before testing, Installed TiurboTweak Emissions Chip, Converter in place. Car was in a shop for a 1 1/2 years in a dirty environment. Passed in 2016. Only thing done to the car since 2016 is replaced AC delco plugs with NGK, Replaced fuel pump. Should I buy a new O2 Sensor (new in 2016) and
EGR (new in 2016). Only about 400 miles put on car in the last 2 years. I have attached the diagnostic report. DOnt want to throw money at the wrong things. Thanks!!
