Legacy05 Posted July 28, 2005 Share Posted July 28, 2005 Not too long ago I had a fuel injector replaced on my car due to a P303 cylinder misfire code. I was just curious, if at idle, if it is normal for the car to shake a bit (idle a bit rough at times). It was really bad when the fuel injector went tits up. So I have no idea if what I am feeling now is considered "Normal" . I am running AP Stage 1. Thanks. Link to comment Share on other sites More sharing options...
melayout Posted July 28, 2005 Share Posted July 28, 2005 Yes it is totally normal. Been doin it since day one and I love it. Like sitting on an ICBM that's about to launch. Dr. StrangeLove I keed I keeed Link to comment Share on other sites More sharing options...
Deer Killer Posted July 28, 2005 Share Posted July 28, 2005 It's normal like other "features" are normal. So your engine isn't broken compared to others, but not any better than that.. Link to comment Share on other sites More sharing options...

Deer Killer Posted July 28, 2005 Share Posted July 28, 2005 Deer Killer - The shake is a characteristic of the Subaru boxer engines.Correction, the shake is a characteristic of the subaru boxer engine when there is a misfire/bad mixture in a cylinder. My old carburated honda used to also get that shake, not the boxer shake, but a tranverse inline-4 one. Readjusting the idle mixture fixed it. We don't have an idle mixture needle.

melayout Posted July 28, 2005 Share Posted July 28, 2005 Legacy05 - Does the shake go away if you hold the gas at 2000RPM? If so then it is just a mechanical harmonic effect happening at that lower RPM and nothing to worry about. I keed I keeed Link to comment Share on other sites More sharing options...

That's with the A/C off .... (I can feel the A/C doing its magic driving around sometimes). Link to comment Share on other sites More sharing options...

I am hesitant to take it in since it is at Stage 2 with Ecutek tune. I'm afraid the dealer would blame it on my mods and charge me what ever ridiculous fees to fix it...
