Q: Enter engine code to get repair estimate??

I have a P0401 error code which has something to do with the emissions system. Is there a way I can enter my error code and get a range of estimates for repair? That would be a handy feature. I would think something like this: Error code P0401 - Emissions 45% cause by bad valve est. repair $350 27% caused by clogged line est. repair $150 20% caused by bad sensor est. repair $400 15% reset code and problem does not return If there could be an added column or two that lists est. cost of parts and or level of difficulty for DIY with links to repair instructions that would be a valuable page and make this site 100x more interesting and valuable to me. Any thoughts?
