nixon Posted February 18, 2005 Share Posted February 18, 2005 Help please. My Forester 2.0 turbo auto has a minor but annoying problem.When decelerating through 45-40 mph[1500 revs] in drive,it stutters for a second or two.Then it's ok again. This only happens after about 5 mins driving,whether from hot or cold. The MAF and o2 sensors have been replaced at subie dealer to cure a nasty acceleration delay,and this has only been noticeable since the MAF was changed,but could have been there before. The exhaust indicates the engine is running rich,but an emissions test shows that under no load the mixture is peachy. I don't know if it's significant,but the fuel tank does not seem to be venting correctly.when refilling,there is a whoosh of air when undoing the fuel cap,but if removed 5 mins after stopping then no whoosh. Could the fuel return/breather pipes be blocked,forcing gobs of fuel into the engine on overrun, or could some other part of the fuelling system be amiss? hope someone can help!
