Default Crap...

Hey all. I'm new to the WRX world. I just picked up my car recently and have been ordering parts for it like no other.

On to the problem(s):

1) Tonight I was looking under the hood of the thing and I saw a rag tucked right underneath the upper radiator hose where the intake bends around and goes into the turbo. Anyways I pulled it out and it smells like power steering fluid. So I'm guessing I have a nice leak somewhere.

2) The car is tuned and running on a safer rich tune at 17 pounds on a 20g turbo. When I get on it sometimes the car will like "buck" when increasing in RPM. I was told it could be the MAF.

3) When I'm coming to a stop the RPM's will drop and then pick itself back up and idle fine. I was told could be the MAF.

4) My AC just went out and I was recharging it and I heard a leak right behind the compressor. Do I need a brand new compressor?

5) The check engine light is on and it brings up the following codes:
-P0102
-P0420
-P0113
-P0546

The car has the following mods done to it:
-20g turbo
-Bigger inter cooler (not sure on name)
-Straight piped exhaust (not sure if it has an aftermarket up pipe)

I'm in the military and I need my car to run flawlessly and I just want all of the problems fixed and have a great car. I was planning on bringing it up to Crawford performance on the weekend and see what they say about it and see if they can replace some parts or anything for me.

Any help?

You egt needs replaced, clean your maf with maf cleaner, and i dont think your car is tuned for the exhaust. I got the same cat code before my car was tuned. After a while the seals in the ac lines go out you can get new seals and replace but i assume if you are on base you dont have the time or the tools. Its all a priority list. I would start with the maf,egt, and retune. You could get a access port. You want your engine to be running first, The egt is in the upipe. Open your hood and look at the bottom of the turbo the upipe is connected to the bottom, if its big bulky and the heat shrouds says subaru its stock. You'll want a catless one for the 20g. Hope that helps, if you have any more questions you can pm me.

Just wait and take it to Crawford. Don't mess with anything let them fix it. They have a good rep for a reason and it doesn't sound like you know much about these motors. You will just save yourself time and hassle in the long run.

Yeah,without listing all the mods on the car we can't help you very much. Was the car not running like this when you bought it?

Seems like the car has a lot of issues. I'd suggest taking it somewhere, a Subaru specialist.

When you try to diagnose something, it could be affected by another issue. It's hard to help over the interwebs in this case.

Good God man.....take it to Crawford and have them fix it. You just learned a POWERFUL and expensive lesson on buying a car. I pray you have learned well from this.

Or you can take it to subiworks up in Murrieta. Ex certified Subaru mechanic with great diagnostic skills. If you want more info PM me and I can give you his contact info. Also a lot of his customers are based out of Pendleton. Not sure if that's where you are working, but if you do and see subies there, chances are he has done some work on those cars.

Or it could be:
A vacuum leak
Hole in charge pipe
Ripped coupler
Dirty iacv
Messed up ground
Dirty fuel filter

Trying to trouble shoot this is like a needle in a haystack. It could be any one of 5000 possible issues.

Take it to Crawford.

Taking it to Crawford this Saturday. Hopefully they can show me everything on the car that I haven't noticed.
