Frustrated In Ontario
My 1996 Intrepid 3.3L engine is to go in for the big E-test tomorrow. Unfortunately this isn't going to happen because my stupid jerked off Check Engine Light came on again. The code that it came up with is *21 which is an oxygen censor but it doesn't inform you of which one. There are two ahead of the Catilactic Converter and there is one behind the converter, how am I suppose to know which one too change without it costing me a fortune? Once you put on the one censor you cannot take it back for a refund. The 2 censors on the front are $102.00 including tax, the one that is behind the Cadilactic Converter is $157.00 without the tax. I plan on replacing every one of them eventially but I don't have that kind of money to fork out all at one time. Can anyone help please?
