Re: Volvo S-60 03, non turbo B5244S, has had check engine...
Replace the cat you have ran it for years with a bad 02 sensor so now replace it and you will get better performance and better gas miliage. Never run a check engine light fo a long time it's telling you something is wrong. youer lucky you did not destroy the engine.
