2004 WRX rough idle

Mar 06, 2005 3 Replies

My 2004 WRX drives fine, but it shakes when I am idling. I bought it to the dealer and they say it's normal. All they suggested to do is to change the fule filter. I am going to do that, but just want to know if anything else could have caused this. Could anyone give me some advise? Thanks


I'm taking my 05 baja in on monday same thing. On the phone the dealer told me this was not normal, some kind of idle adjustment. I'll let you kown when I get it back.

My 2002 WRX shook at idle, and so does my '04 STi. It's a slight shake in my case, but certainly noticeable enough that my wife turns the ignition off when I let it idle and leave her in the cab for a few minutes. She misinterprets it as a cold-engine-like behaviour common to older domestics that are about to stall, but from -30C to 38C neither car ever did...

I.e. I wouldn't worry about it. If your car goes into limp-mode then there's something to start wondering about--but otherwise try to get used to it.
