Hey all! Last week my dream came true when I bought a 2001 Impreza RS sedan. But there is someone thing that I question about the car when it idles. It seems kinda rough when the car sits in park. Its kinda a choppy, inconsistent idle. As soon as i put it in drive, its fine. The car only has 12,000 miles on it, i just did an oil change, and added fuel injector cleaner. Is this normal? Should I check the Plugs? If anyone has any suggestions or thinks this is normal, please let me know. If you live in the Philly area let me know, Im looking to get together and show off our rides.
