cindy1956 Posted November 18, 2015 Share Posted November 18, 2015 My Subie has had an ongoing exhaust problem for a while now. This car's saga is long, but I won't take up space here. Noisy exhaust, gray-blue smoke out the tail pipe, had to keep my foot on the gas on start up to keep it from dying, possible choke issue as well, etc. After a long drive (500 miles) to visit my daughter, the problem seemed worse. A couple of days later, I heard a soft pop and the car seemed to run much better. However, it started to auto-rev at start up—up to 2500 rpm then back down. Once the car warmed up and I started driving, it seemed fine. A day later (yesterday), it started to auto-rev whenever I idled. Tonight, on my drive home at highway speeds (55 mph), it started auto-revving at those speeds, and was going into the red. I had to pull over and stop three times within a couple of miles to let it calm down. Also makes an horrendous grating squeal when revving, as if a belt is rubbing hard. Help! Not a mechanic and I wouldn't know what looked normal and what didn't if I were to crawl under there or look under the hood. Quote Link to comment Share on other sites More sharing options...
l75eya Posted November 18, 2015 Share Posted November 18, 2015 (edited) Hi! To better assist you, could you give us the exact model subie you have? You mention the choke so I'm assuming it's carbureted. Edited November 18, 2015 by l75eya Quote Link to comment Share on other sites More sharing options...
