My emissions problem light came on and I took it to Stockton 12 Honda in Salt Lake. They said it was faulty fuel injectors. They are not blocked but allowing too much gas into the system causing excess emissions. My vehicle is a 2017 Ridgeline RTL-T with 45,000 miles. I have a long commute to work. Anyway, they want $1,500 to replace the injectors and associated equipment. I have used "Ethanol clear gas since purchasing the vehicle. The service rep said it is been a common problem for Ridgelines and Pilots with high miles in a short period of time.
