Hello, the engine is knocking like it has an octane problem. Also, it has a really rough start when starting cold as well. It will start up fine when warmed up. It seems to have no driving issues although it seems like its runs rough when taking off. There is no check engine light and the fuel filter has been replaced. The injectors have also been cleaned. Any ideas?
