SOURCE: Cylinder 1 misfire on my subaru!!

What you should check first is the spark plug for the #1 cylinder and see if there is a white film on it this would be a sign of a coolant leak which would cause a problem with the O2 sensor

SOURCE: EGR Flow Malfunction, and sometimes a Cylinder 4 Misfire.

How does the oil look? Is it milky or is there any discoloration? Is any moisture or steam vapor coming out of the exhaust pipe? The EGR fault is most likely being triggered from the cylinder missfire. Sounds like you might have a head gasket blown, and/or a cracked or warped cylinder head from the overheating.
You can run a compression test to help determine this.
Good luck...i hope this helps you troubleshoot the problem.

SOURCE: what does the diagnostic code P2181 mean on a Subaru Impreza WRX?

this is a coolant performance code. Usuallly sets this code if the connector was left unhooked to the coolant sensor or the thremostat is stuck open. By any chance do you have a gauge that seems to be on the cold side ??

Usually a vacuum leak will make the idle bog down rather than speed up, even if the ECU is compensating. It will be rough, but as you say, it's fine through the revs.

This leads me to think the PCV (postive crankcase valve) is not connected or is leaking. This raises the idle, although the ECU will suspect the IAC to be the problem. Check the PCV valve first.

Check the MAF sensor for dirt too.

Another point to make is the throttle body might be clogged/dirty. Get the intake manifold off again and clean it with petrol/carb cleaner and a toothbrush, check the condition of the rubber seals, if they are gunked up, the air speed will increase, causing a high idle. Check the exhaust manifolds for any build up/rust.

Finally, when were the O2 sensors last changed? If recently, are they the right way around? If not recently, try those, but make this the last resort as they can cost a lot.

I hope I have covered every eventuality as I can see how annoying this is for you. As you already mentioned, reset the ECu after each attempt.

Good luck, fire any questions back if you need.

Voltage Regulator?

If the noise sounds like a weeeeeee that increases in pitch as the RPMs increase, and you haven't heard this sound before the 'problem', suspect the alternator...

I bought a 1995wrx turbo japanese import 260bhp standard,which can only run on v-power 99octane fuel,from scooby clinic in chesterfield (scooby race tune expert mechanics).I was the first person in england to test drive on road (it had not long arrived in the uk & had been put on rolling road a few times),whilst test driving,the turbo boosted normal & then started juddering slightly etc etc,i asked scooby lad "what was that" he wasnt sure(office boy!) & assured me that whatever it was theyre top mechanics would sort it out & do a full service,change the belts etc etc, i bought it,luckily with a 30 day warranty included starting from collecting it.I picked it up about a week later,i got as far as 20mile away(nearly home) & it started juddering again,nothing too serious,so i thought we'll see how we day same again,after 3days it were juddering more visciously,getting worse to the point where i nearly hit the windscreen,i thought its got to be a fuel blockage?.it backfired twice & not long after that packed up & would not start again,i foned scooby clinic & towed car back up to chesterfield.they kept saying "i must of put wrong fuel in",they ended up taking engine out cos head gaskets had blown,engine had died,6-7 wks later they told me to come & collect car with no charge,i was told to run it in for 500 miles steadily,& then take it back,they then changed oil,sparplugs & boosted turbo back up(re-connected it),the boss apologised to me & said if he knew it were like that he would never have sold it at all to anyone,he explained that the engine was carboned up(blocked) they did a nearly full engne re-build free of charge.the boss said if he knew it were blocked up they would of gave it a thrashing to clear the engine.
