Hi guys, I'm new to Subaru's.
I own a 2004 WRX, with only 14,000kms on it. I have a little issue. When I step on the gas, I get a shutter throughout the powerband. Almost like a misfire. Sometimes worse then others. The car also idles a little rough. I was told the plugs don't need to be replaced tell 100,000kms. I'm only getting 450kms to a tank, does that sound right? Any idea what to look for, it's still under warranty.
