P0171 is "system too lean bank one" but from what I have read and even though I have read a lot I may not have read everything it is one of those ghost codes that people chase over and over till they go crazy or broke. I will start looking for dry rot but I really looked pretty hard prior to buying the car because of what I had read on here and it all looked pretty good. Oh well, I'll keep posting on here and looking for suggestions. Thanks
