Nothing changes, very low.
starts, dies immediately
Vehicle: 2001 BMW 325ci Manual 250k miles
After having a rough idle and getting lean bank codes to be exact: Fuel Trim bank 1 Control limit, Fuel Trim bank 2 Control limit, Misfire on all cylinders and Fuel Trim Bank 1 & 2, Permissible range exceeded. I replaced my CCV, Intake boot (Lower and Upper) SAP vacuum line, and the non-return valve vacuum lines following the 50's kid video. Once I removed the Intake Manifold (IM), I found out the previous owner removed the vacuum canister and plugged the hole in the IM. Not knowing what to do I continued to replace everything double checking everything was plugged in. After I finished installing everything, the car would start then very rough idle and die within 2-3 secs. The codes I pulled are: System too lean Bank 1 & 2, All Cylinders Misfire with fuel cut off, and Multiple Misfires detected. I'm sure my vacuum lines are in the correct location and plugged in, could this be something like me accidently moving the throttle body flap? I'm worried I messed up. Also the air duct from the front of the engine to the airbox is missing don't know if that would be affecting my prior bad idle.

No need to apologize, we were all new to cars at some point in time. I would suggest that you don’t simply pile on one problem after another in the same thread. Otherwise it’s really hard to follow, difficult for others to search and we end up with overlapping conversations. Lastly describe your problems clearly with details as that would get you the best responses.The air blowing from the interior A/C is very very weak so I’m guessing the fan blower. I was referring to such when I said nonexistent, I’m not yet familiar with the A/C system, my apologies.
With that, how about we keep this thread to be about your original problems?
That’s totally fine. I’m going to replace my fuel pump this week, that should fix the fuel pressure issue.No need to apologize, we were all new to cars at some point in time.

Great, let us know how it goes. Posting the end result is very useful for everyone. The people who helped would get a sense of accomplishment because they helped someone. If it fixes the problem, then when the next person searches this forum, they would get everything they need to help themselves.That’s totally fine.

How many bad coils you had? one bad coil wouldn't cause the engine to die.then would die a second after it started.
Not saying with 100% certainty that's what's causing your issues, but in my case it was a bad coil...
I got a brand new valve cover, coils, and spark plugs thinking it would solve my problems. Bad idea! Fixed nothing.
So what did you change that engine was not running and then now idling perfect? Obviously the low fuel pressure is not good.I have great and bad news.I doubled checked all my work but it still wouldn't start, checked fuel pressure while cranking it was 30 PSI. I cranked it then revved to 2k rpm for 10-15 secs turned it off then turned it back on and now its about 45 psi and idles perfectly,
I would use it.To get free shipping im going to buy everything on fcp euro, so is this a good filter?
