Hey Guys,
I need to have an emissions test done on my car but I know it will not pass with the CEL on. The CEL seems to come and go as I drive and I don't notice and driving issues. Here are the codes I get:
511 - No worries I have a chip installed
173 - 02 fault rich
177 - No 02 sensor switch
179 - Fuel system lean
188 - Fuel system lean
Thoughts on the cause? Am I looking at new O2 sensors to fix this?
