Yeah I agree I need some kind of better software. It has had brand new downpipes put in at dealership last year. Which if memory serves the catalytic converters are in the downpipes as well as injectors and coils and spark plugs and a whole bunch of other stuff all last year. As you said I have a feeling the reason they sold it to me is because of this reoccurring issue, despite them spending a lot of money to resolve it. The kicker Is the vehicle runs fantastic, it's a bummer the check engine light keeps coming on, because it seems like it's coming on for no reason. It runs exactly the same with the light on or off
