Soo the past week my car has been idling around 750. For the past 4 years it has been idling at around 1000. The car sounds a bit different too. When i give the car gas it seems to run fine though....any ideas?

May I jack this thread to ask what I can do to fix that?

If you both have an issue with the idle changing (i.e. sometimes idling at 1000 RPM and other times idling at 750 RPM) when the engine is warm, I would check the IAC valve integrity. Although usually an IAC fault causes the engine to stall or rough idle...

I got the throttle body and the throttle body plate cleaned. It had carbon build up in it. I figured it would fix the problem but it really didnt. My engine just sounds really putty right now...which is lame when im sitting in traffic. I still dont udnerstand though why it would change idle after 4 years though.

It's called the boxer rumble. Honestly, boxer engines typically sound like they are going to implode at any second...

Maybe i should just face the fact that my car is getting old. 93k miles on the old girl. I should just give her a nice buff before the winter time and cheer her up.

2007 WRX and STI
idle rpm at park: 700 +/- 100
02-04 wrx is 750.
The way to check is to pull your rom - the idle control things dictate where idle should be...
...what makes idle be low? what should I check?

You're at 700 rpm currently? There will be slight variation from car to car, weather conditions play a role, accessories running, etc... I wouldn't be concerned unless there's something else throwing a red flag.
I would be more concerned about why the car idled at 1000 RPM for 4 years without changing the IDLE RPM parameter

More than likely looking at it incorrectly...
I remember looking at my idle on my STI and realizing the first hash marks on the tach didn't actually start at 0...

how could i possibly look at it wrong? Its almost impossible to confuse 1000 with 750. It just changed one day...or maybe i'm just going crazy. In any case....I will pull the IAC on my next day off and clean it. If it doesnt fix the problem....then its probably not worth it.
