Did the all 8 fuel injectors/plugs/coils over the past month as my 'Quarantine' project since I was able to take a liberal amount of time off without any real consequences. Anyways, to do the injectors wasn't an overly bad job, I just disconnected the battery and started to remove whatever was in my way. I cant stress enough about writing down steps you have done because when its been a few days and a few beers you forget things you've removed. Made a mess with the coolant removing the heater pipe on the drivers side but disconnecting the fuel hoses/lines was less of an issue than I had envisioned. Followed the procedure TO THE 'T'. Even got ISTA+ installed to do the calibrations and reset mixture adaptations. Got everything buttoned up did the ISTA+ procedures and go to start it up with fingers crossed.

Thats when the real fun started, holy mother of god. It ran like complete dog shit, couldn't idle, and started to detonate in a cylinder. Turned the car off immediately and gave a 'I fucked up sigh'. Tore down the engine AGAIN to see what it could be. Went through and double checked everything, buttoned it back up, go to start. Same thing, sounded like a big stumbly carburated V8. Decided it had to be a vacuum leak.

Ordered new turbo inlet pipes since the plastic was broken thinking that could be some of the problem. NOPE.

Then I finally found it, buried deep on the drivers side where only children's hands can fit, the Crankcase Vent Pipe was completely disconnect off the intake manifold leaving a 1" hole of a vacuum leak. It must have came loose when I was removing everything. After a few beers and over an hour I finally contorted my hand enough to pop it back on. Clear Faults, Delete Adaptations, and BINGO car was back alive.

After that the car ran fine for a week until the same crankcase vent pipe came apart, this time the actual pipe by the connector split. I have a new one on order.

I would love to know the thought process behind using this plastic hose or if there is anything better I can replace it with in the future.
