2004 Toyota Highlander, 2.4L engine
124,xxx miles.. passed smog earlier this year
My wife was driving when the check engine light came on. I figured it was the gas cap, because I usually fill the tank for her, but she did this time. I had also just changed the air filter, so thought it might be a loose hose too. She kept driving with no issues to Reno, NV for the past weekend. I drove it home yesterday, no issues at all, same good gas mileage, etc. Checked the code, P0420 and cleared.. it will most likely come back.
any good recommendation for an aftermarket Cat? I have looked and the O2 sensors seem to be about $120 to $150 each.
How do I tell whether its the O2 sensors or the CAT?
