I have a 98 camry u.s. 4 cylinder with 125,000 miles on it.
Just bought it and have a new air filter and new plugs.
I am wondering what different items will cause this to burn rich or do all camrys have a black or close to black exhaust pipe?
Looks like original oxygen sensor.
Thank you for your help.
