Question about 1991 Subaru Legacy
The check engine light comes on and goes off. the knock sensor has a crack in it, so the local mechanic put it on a diagnostic scanner and everything came out okay?? it recently had a new battery fitted and the codes may have been lost. when the reeves are up it runs fine, but when the reeves are down it is really rough like it is trying to run over lumps. also as we have not had this car for long, where are the fuel filters located? thank you
Your car is not OBD-II, some dealers still have the Subaru Select Monitor required, some haven't kept them. Your local mechanic is unlikely to have spent $2,000 for a tool that only works on 15 to 20 year old Subarus. You can read the check engine light codes without any special tools though, see http://legacycentral.org/library/literature/codes.htm
The fuel filter is right next to the windshield washer fluid tank.
