Knocking in engine system too lean bank one 1& 2 misfiring should I fix it? Or just sell it? Body and interior 9 &. 9 always kept it well oiled and every Friday. Brushless washed black still pretty in and out. Waxed a few times a year no rust etc. Worth to fix or no?
You should really have the knock diagnosed first before making any decisions on moving the car on, just keep in mind that as it sits now you will have a hard time selling it and you will not get market value with the current problem it has.
