RE: Code 522,123 and more - much worse - need help
At sheer idle without a compressor on, Im a bit higher than 20. Maybe around 21-22mmHg. However the gauge may not reflect a vac leak that is present in the brake boosting system. My gauge didnt show anything out of the norm when I lost my brake booster.
Now heres my final suggestions. Before you take it in again. Return it to Stage 0, take all of the Stage 2 stuff out, (not that much really) and put the stock computer back in. And remove the OCC off of the PCV valve. Then see if the conditions are still present. Of course excluding the TPS issues.
This is pissing me off that I cant give you any solid ideas as to what it could be. E-mail RIPSIGUY, he deals with problem vehicles daily....see if he has any other input to give you. He should get back to you by tomorrow. Dont PM him though, Email him. Hes not always on here thats why I say that.

I'm reading and reading and I'm thinking strange, wow, hmmm and strange again.
My feeling is that somehow a lot of this is related but I think you have at least 2 seperate problems.
I have a lot of questions too.
What temps engine and ambient is the oil issue happening at?
What is the oil level?
What is the oil viscosity?
Do you have any oil thickening additives in the oil?
Did you hear low oil pressure noises like ticking?
When you took off from stopped engine to give 'er hell, what kind of time frame are you talking?
Did you back up then go forward or just nailed it?
Have you been driving in the rain?
Is there water in the power panel or in any connectors? (salt water is especially conductive)
When you push the brake, what does the vacuum gauge do?
What are the codes?
What is your name?
What is your favorite color?
Check all your connectors, grounds etc, really good.
Most of my electrical problems which often look like computer problems are corroded connections maybe 50%, broken/chaffed wires30%, bad sensor 20%
Bad computer/other 10%.
Hey I am a mechanic, I am allowed to go over by 10%.
On this car, a vacuum leak could in some way be caused by an electrical problem I suppose. (air solenoids)
I really need to look at my CD's, they should have the codes and should help me diagnose these kinds of things. The more I learn about the trucks I work on, the more I realize I don't know about the car I drive all the time.

Things still point to a vacuum leak. Try this while at idle, stomp on the brake pedal and see how much the vacuum guage moves. It should hold a steady vacuum while your foot is on the brake pedal, right? If it moves around at all while your foot is planted on the brake pedal (after the initial drop when you first push the pedal), I'm sure it would point to a bad diaphragm in the brake booster, or a vacuum line very close to it.

What temps engine and ambient is the oil issue happening at?
any - it first happend cold. most recently it happened at 70 on the turnpike at around 195degrees
What is the oil level?
normal
What is the oil viscosity?
5w30 mobil 1
Do you have any oil thickening additives in the oil?
no
Did you hear low oil pressure noises like ticking?
no
When you took off from stopped engine to give 'er hell, what kind of time frame are you talking?
pretty quick like 3 seconds from start to driving, but not really giving her hell, more just normal driving, just in a rush
Did you back up then go forward or just nailed it?
not sure
Have you been driving in the rain?
yes
Is there water in the power panel or in any connectors? (salt water is especially conductive)
not that I noticed, but I'll look and check and get back to you on that
When you push the brake, what does the vacuum gauge do?
it goes from -20 to about -16 then settles around -19
What are the codes?
p0123, p0522
What is your name?
sir lancelot
What is your favorite color?
red, no yellow...ahhhhhhh!!!!!!

will do

I was thinking that the tps could false the wastegate solenoid and cause some of this...Jason agreed

Was there oil in the connector for the oil pressure sender?

Update after they had the car overnight:
They replaced tps and road tested, didn't get check engine light or oil light. Cut convoluted tube off of wiring harness to oil sensor and the splices for the tps wires, didn't find any issues. Will be running new wires from pcm to tps and oil sending unit. Haven't been able to duplicate the brake problem, but I think one of their rental neons did the brake thing awhile back on a rainy day. They are going to call the STAR Center (technical support) to see if they have had any other cases like this.
I still have the loaner at the moment - but is looks like I am picking up the SRT-4 today - hopefully the engine is back on track. For now the brake issue is still unresolved, I hope we figure it out soon...28,000 miles of driving with an occasional, unexped loss is getting tired.
Did you read through all the comments I had? I hear you might be a good source of advice, RIPSIGUY.

These brakes in the rain pick up alot of moisture causing a condition similar to that of losing your brake booster. However in the rain you never actually "lose" the booster, but it does feel that way. Its ESPECIALLY problematic with my Stage 1 brakes because their cross-drilled. The water wells up in the holes and stays there.
Dont feel bad. I have almost 40k miles of driving and continuous problems LOL.
Email Paul, (RIPSIGUY). Its friday so he wont get back to you until monday, but its better than typing something here. He may not get to it that way.
