I went to pep boys, an auto parts store/garage, and got a tune up.
explicitly I went for new spark plugs. they told me my gasket was leaky, which it was. I told them I wasnt getting it done that day, and certainly not for the 300 they wanted.
I got it fixed up at another shop, and when I was still having issues with a misfire I checked the damn things myself. They installed a bad spark plug; one that looks like they purposely fucking damaged. Complete with touching bitties and wear on the top by the plug itself. Fuck them.
Fucking Friday, 3 days ago now. That is 3 days old.
