Just after I bought my Boxster S 6 years ago it through a CEL, a completely new arena for me. At the time I put the car on the ramps and found both os's on the cats were loose, I tightened them up and that solved the problem. Did the disconnect battery thing to get the light off.
6 years later, yesterday in fact the CEL came on. There is no noticeable difference to the running of the car. It always pulls like a train without hesitation and its no different now with the light on. At this point I might add that I do all my own maintenance of my car. Having said that I have steered away from diagnostic equipment and up to now have managed fine. I had the car on the ramps today and there is no loose os's and it sounds sound sweet underneath with the motor running and there is nothing i can visually see wrong.
I'm cornered now so two questions, is it worth asking what any of you guys think it could be? Also it seems like I am forced into considering purchasing a diagnostic tool, which one though, its not my area? I do want to continue doing "all" my own maintenance.
