Why does a 2000 Subaru Forester start fine run for 25 minutes stutter badly for 10 minutes then run fine once again?
Answer . \nI have a 2001 Forester. I have learned the Foresters in general have a very sensitive exhaust system. You problem could either be the o2 sensors or the cataly…tic converter. Most likely the converster with should be porcelein I think. The cheap way might be to find a mechanic who will be willing to clean the converter (the honeycomb things) and see if it runs a bit better. Good luck! (MORE)
