I need help repairing my 2006 Subaru B9 Tribeca. It lost power while driving several months ago. It has 256,000 miles on it. After a tow, mechanic said it has good oil and gas pressure and is likely an electrical issue. The engine turns over, but does not start. Mechanic estimated 1-2 thousand dollars’ worth of repairs, so I did not proceed further. For over a year, it had been reporting an engine misfire. I tested all spark plugs and coils and could not find any issues. I briefly posted it for sale, but considering the current car market, I would like to explore more options for inexpensive repair. Can anyone help? Please advise, thank you!
