2003 Forester Standard
Im extremely new to this forum but ive had my forester for little over a month. Its a 2003 2.5 non turbo, standard transmission with 209,000 miles. When we went to buy it, it was missing EXTREMELY bad. The whole car would shake. After a few times of shutting her down and starting it back up it seemed to clear out so we drove it home. (About 45 minutes away). The next day i went to start it to go to the parts store (ironic) and it was missing again. I brushed it off and kept going but now it was stalling, every time i let off the gas. I got it back home (3 mile drive in a circle) and found it was the ignition coil. Cylinder 1 had no spark at all. I pulled the plugs and 2 of 4 were completely worn out. There was no tip left. So new plugs, new distributor, and it now has a knock. Ive put over 2,000 miles on it and still the same exact sound. Other than it sounds horrible when its cold. When its warm, its still there but not as bad. The knock completely leaves past 1500-2000 rpm. If i drive for 20 minutes, it will sometimes disappear. If i shut it down and restart it the sound comes back. The knock is most prominent from the injectors. More so on cylinder 4. I just dont know if I damaged something from that 3 mile drive on 3 cylinders or if it was a sound waiting to surface. If so, is it okay? Or am i looking at the price of a rebuild/new motor?
