Yay! Another Misfire and Stall Thread (with data - Sorry)

I know I'm going to get beat up for this one. And yes, JFOJ, you are the stud when it comes to chasing these down. I have tried to do what I can to prevent any issues but...surprise!!! No matter how much preventive maintenance you can do to your E46, there is ALWAYS going to be something else.

History of the car...

2002 325Ci 72,000 miles
New Fuel Pump
New Fuel Filter
New DISA O-Ring
Cleaned MAF
Cleaned Idle Control Valve
New Valve Cover Gasket
New Spark Plugs (Didn't do boots, that might be a problem)
New Cam Position Sensors (Both)
New Control Arms (not that it matters)

I performed a smoke test and I see NOTHING!!! Tried it several times.

I know the last things to try is the CCV/Separator and it looks like I have a recurring theme with Thermal Oil Level Sensor??? What the heck is that? Also I had a Thermostat stuck open pop up on one of the scans. Its on my list but will it really be a cold start/Stall issue? VANOS??? I hear a faint rumbling...I want to do it. But is it a cause?

So here is what I have. Hopefully you guys see something...
The only difference between the 8-1Scan and the 8-13Scan are the new Cam Posi Sensors.

Thanks again for everything guys!!! You are awesome!!! One thing I did notice is I seem to have a lot of crud on the top of the cylinders. I saw the Youtube where the guy pours upper cylinder cleaner in. Maybe I have a stuck ring on a piston???

I am at your mercy....

Really need to change a few things here.

Read this thread about setting up Touch Scan - http://forum.e46fanatics.com/showthread.php?t=1080334

Seems from PA Soft that cylinder #5 is popping up on the radar. The short burn time may be due to a Lean problem or it could be a questionable coil. You would move #5 coil and see what happens.

You really did not describe the problem, just misfire and stall. Is this on cold start and only on cold start?

Data you are providing is not really enough.

You need to set up Logging and Log 4 minutes from cold start letting car idle, 3 minute at warm idle and 3 minutes at steady highway cruise.

Set up a DropBox Free account. DO NOT INSTALL the DropBox software on your computer, it is not required and bloats things up. The put your DropBox account info in Touch Scan and you can easily upload info to DropBox.

Then you can paste the share link for the .CSV files back for review.

Assume you have verified the DISA, Brake Booster, Intake Boots and ALL the CCV hoses are good? A smoke test goes a LONG way and saves a LOT of time chasing your tail.

Good luck.
