I bought my Subaru about three years ago with only 26K miles. I got a really good deal and could not pass it up. The car for about a year now randomly will not start. It will crank and it almost sounds like it mis-detonates (fires on two cylinders at once stopping the cranking from the starter) and does not start. After a couple tries it fires up but revs rough and smooths out. Very troubling, anyone else has this issue?
