Catalytic Converter Going Bad?
Catalyst Monitor does not run on my 2004 Crossfire 174,000 miles.
Replaced 02 sensors and catalyst monitor sensors, vacuum lines.
Im at a loss. I do not have any codes. LTFT is at 14 %.
74mm TB, NeedsWings Intake. I put the stock intake back to see if the monitor will run but didnt. Im in California. 2 years ago the car was smogged.
