With thanks to Larry Caley:
(Highlights in red are my edit)
MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR. The MAP sensor is mounted on or connected to the intake manifold to monitor intake vacuum. It changes voltage or frequency as manifold pressure changes. The computer uses this information to measure engine load so ignition timing can be advanced and retarded as needed. It performs essentially the same job as the vacuum advance diaphragm on an old fashioned mechanical distributor.
On engines with a "speed density" type of fuel injection, the MAP sensor also helps the PCM estimate airflow. Problems here may cause an intermittent check engine light (light comes on when accelerating or when the engine is under load), hesitation when accelerating, elevated emissions and poor engine performance. The engine will run with a bad MAP sensor, but it will run poorly. Some PCMs can substitute "estimated data" for a missing or out of range MAP signal, but engine performance will be drastically reduced.
MAP Sensor Strategies: Some MAP sensor problems are not the fault of the sensor itself. If the vacuum hose that connects the MAP sensor to the intake manifold is loose, leaking or plugged, the sensor cannot produce an accurate signal.Also, if there is a problem within the engine itself that causes intake vacuum to be lower than normal (such as a vacuum leak, EGR valve that is stuck open or leaky PCV hose), the MAP sensor's readings may be lower than normal."

Alright...
Thats bring's me back to the PCV... I cannot plug it back in or the car will not run... this is turning into a vicious circle....

Your quote:"Well than weather its hooked up or not all that access boost will just vent to atmosphere than yes? So that probably isnt throwing any code than... it shouldn't make a difference either way...."
The pcv has no psi/boost in the system. The only thing that would vent to atmosphere is any psi from the crankcase. This is not the problem.
At this point with your codes it shows at least to check the voltage of the 02 sensors and/or field test operations voltage. Or just get a new one.
After reading the good book information from Ancient mariner I pulled a known bad o2 sensor and installed it in the 06. After running for 5 minutes it threw a P0030 code.

to Nitrominis.But...
Didn't you say you changed both sensors already? If so, was it with the universal type (cut and splice wires) or with OEM equivilant (plug 'n play)? In either case, it could be a bad connection (very low current flows in those circuits, easily disrupted by poor connection). Establish the cause of the P0030 code and work outward from there.
We'll figure this out yet. Have faith.

I am still thinking about the stalling when he connects the pcv line??
That just does not make sense ? The air volume would be the same?

PVC line drawing some vacuum? Not sure how or from where. Did he say what year it was? I need to look up some diagrams but I'm needin' the year.
I'm sittin' fat 'n happy in my 02 justacooper, so I can't do any eyeball testing to see what's happening.

but its fun if you solve problems. You better watch out for the guys who hate the labeling of "justacooper"
I think I removed all my S's so what does that make me but "there goes another Mini"

Hag, just wondering: when you said "right side of the engine", did you mean right side as you're facing the engine (driver's side) or right side of the engine (passenger's side) as you sit in the car?
Nitro: I had my MINI long before the "justacooper" term was being used. When I got it, I mostly heard "what kind of car is that?" It was still pretty rare, and none of us thought about S, non-S or whatever. Just tickled to have one of the little buggers. Still feel that way after six and a half years.
And, yeah solving problems here is a blast. Maybe we can drag some others in for additional input. Or muddy the waters completely.

Mine is an 06/02 and got it shortly after. I have always just called them all Mini's.

"The youngins will always will do that
I had to call Rust-o-leum tech today. While on hold I was entertained with their history. Did you know it was a ship Capt. that noticed the oil from the fish prevented the rust from forming where they laid when pulled onto the boat? And from there the company made its first product? Hahahahaha . I thought of that looking at your avatar. Now I will think of you as the man from Rustoleum hahahaha.Or dead fish...hahaha

Maybe we should post this on the "Rusting door frame" thread. Tell people that all they gotta do is rub the car down with dead fish (I think maybe salmon 'cuz it's high in the omega's that are good for you), and "Ta Da! No Rust!"
I now return you to your regularly scheduled thread.

better then looking at a diagram. this was posted on another thread. That line goes from the SC to the PCV valve.
Just thought you might want to see a picture.
Oh and there is no rust on the sc which was pre coated with Salmon oil

Haha.....
SWEET!!!
So how can this line being just a dumb breather line cause so many issues???
I plugged it back in today, (the line), and drove around town to run errands hopeing the ECU will "relearn" it maybe... so we'll see.... haha

Yeah...
to use the latin, screww the dealer. Check Classic Auto Campus, also the BMW crowd was having good luck from Pellican Parts, and if you go to www.bmwcca.org and read around there, a couple of lower cost 02 sensor sources are listed. Down from about $2 bills to $80 bucks....

So Doc...
While I have your attention on this thread... what are you professional thoughts on this PCV valve issue???

Aren't you suppose to be working on something?

I think that British Atlantic has them on sale right now.

Try giving your local auto parts a call you may be surprised. Not like kregans or pepboys but a real auto parts store.

Whew! This thread managed to pull up just before it hit the ground!
Maybe.
Silly question, Hag, but are you clearing the codes between fiddling with the problem? If it's staying in "limp home" mode, it will just be adding to the confusion.
and Nitro, a pint of fish oil in the tank keeps the injectors running really great. The down side is that any one following you thinks you are doing delivery for a fish 'n chips shop. And the cats. Oh, lordy, the cats!
