Watched a few videos on youtube. Looks promising. I have heard about seafoam before. Just never used it on anything. Of course nobody around here carries it. I will order a can online. Should be here some time next week.

I have tried all the suggestions and have changed way too many parts and this car still runs like crap. Just did the fuel injectors last week. That was my latest thing and yes, I did the Seafoam thing. Did not make any difference. In the end since I can't get rid of it I'm going to have to take it to a shop and see if they can figure it out. Tired of a car that runs bad and gets horrible gas mileage.

I still think it is a VAC leak
Seafoam is not a performance additive. It basically cleans your engine out.
If you have a lot of carbon buildup it will loosen it up helping your engine run like it should. If you don't have a lot of build up you won't notice anything.

I cleaned it. Then I replaced it. That was the first thing I did almost a year ago.

Ok, I have a vacuum gauge hooked up right now. At idle it is pulling 12 1/2 inches of vacuum. If I push down on the gas pedal real quick it will drop all the way to 5 but recover right back to 12 1/2 inches. Is that what it should be pulling?

Should be around 20 you have a massive vaccume leak

That's what the gauge was telling me. It showed at idle it should be between 17 and 21. Well I guess I really got to try and find it.

Well, I discovered that if I put a clamp on the line that runs out of the top of the intake manifold that runs down and has a T that runs to the turbo the vacuum comes up to 20. I changed the part of the line from the manifold to the T. Still has the problem. If I clamp it, The goes back to 20. So it looks like it's the line that goes off from the T down to some sort of actuator on the turbo. Engine is hot right now so I can't get at it. Looks fine though. The line I changed out was so brittle. That is the line from the manifold down to the T. It broke off at the T. Can anybody tell me what part that is on the turbo that has the vacuum line going to it? Could it be faulty?
It is called the wastegate actuator (WGA for short) and yes it is a very common part to fail. I had two OEM ones replaced in the first 50k miles. I've had the ATP replacement on since then with no problem. Normally, you end up overboosting and hitting ignition cut before the actuator is bad enough to start allowing air to be pulled in at idle, so hopefully that's still ok.
To check, disconnect the hose from the T going to the WGA. Blow on the end of the hose to see if you can blow through the WGA. If you can, it is faulty. Either way, it sounds like you need to at least go buy some new hoses and a T adapter. Autozone sells them, although they only carry a variety box of T's with a lot of sizes you'll never use.
You could also have a leak at the bypass valve which is where the other branch of the T is going, so check that hose and connection for leaks as well, although it is not nearly as common.

Is this the ATP replacement part?:http://www.atpturbo.com/mm5/merchan...p&Product_Code=ATP-WGT-011B&Category_Code=WGT

Vac leak, it is time to replace as many of the 9 year old hoses as possible

It's not the WGA. I just tried to blow through it. Could not blow through it at all. The 2 brittle vacuum lines I took off as 1 piece. Put my fingers over both ends and blew. Could not hear any leaks. Guess I will go to the parts store and get some vacuum hose and some new T's now. Try that and see if I can solve this problem.

All of them were from the same year and batch number.. If one is weak and cracking, then they will all be the same...
I bought mine from Protege Garage, but it's probably the exact same part. Doesn't sound like you need one yet though.
