I had the check engine light come on. Shop changed the catalytic converter but said it may also be the 02 sensor but wanted to see if the converter fixed the problem first. Light came back on. I have priced 02 sensors and I believe I can replace them myself My question is should I replace both the up and down stream sensor, or work my way from up to down to see if the problem is solved? Also, is it hard to reset the check engine light?
have the same problem?
