Hanky, I would gladly post all of the scanning info that I have as picture files, but I haven't found a way to do it on this platform. I'm not sure what you mean about "engine data stream". Is this scanner or the scope data? When I drove back to my apartment the motor begain missing very strong at idle, and almost no breaks.
The vacuum valve to the booster separated in two. No engine alert light was displayed.
Take another look at my previous post, I made an edit after you posted back.

 

That broken check valve to the booster surely has something to do with excess air getting into the engine. That location will never get reported to the vehicle computer.

You may have found the cause of the problem.

Data stream consists of things like , engine temp, RPM, injector on time, Mass air flow in grams per sec,,long and short fuel trim, oxygen sensor switch rates, voltage, etc.

Your friends scanner should be able to provide that info. The object of all this is to know what a reading should be versus what the tool is showing.

The best comparison I can say is like the doctor when he looks at your blood work. If the person doesn't know what is normal and what is not is no help.

 

The scannes were done at this rpm.

 

Still trying to load the scanner pictures.
