Hi all. I have a 2009 Impreza Outback Sport that is doing an immediate stall in reverse only. 180k. Head gaskets, valves, timing belt and wp all done when I bought the car at 174k. No other issues. Just did plugs and wires last month. Scheduled maintenance rn is fuel filter and trans and diff checks. The car idles in park and neutral and will drive forward just fine. No coughing or spluttering or misfire, just dies immediately in reverse. My fuel light is on rn, could it be a dirty injector issue? Any other suggestions that I can look into would be appreciated!
