There was a lot of discussion around the time of the Evolve-R group buy. Anyone have success with that?
How many miles on the car? I would replace all O2 sensors. These sensors fail pretty regularly on our cars. Also don't buy from dealer. You can get the Bosch sensors which are identical for a fraction. Good luck
