Cat problems
Driving a 99 civic si with 170k on odometer back in march I installed a new cat its an oem style eastern catalytic cat i purchased for around 120 bucs. Just this week I got a p0420 code. I don't understand could this cat be bad already. When i first installed it I got a o2 sensor code which i cleared and never came back.
My Mechanic who works for honda for over 20 years and is a good friend said its definitely a bad cat. Anyone else ever run into this.
