I hate my pig but I love my pig, can anyone please help me before I send it for scrap. Over the space of the last 4 years of ownership my car has been in the Porsche dealers for 2 years in total with suspension problems, to cut a long story short this is now sorted and was due to a faulty replacement air bag being fitted. Moving on after 3 months of (almost) trouble free motoring this is what’s happening now and would love some advice as the closest porsche dealers is over 200 miles away from me.
When I picked up the car from Porsche it ran out of petrol before I got to the garage at the end of the road and although I filled it up it the engine warning light remained on I assumed this was just fuel related and drove home with it on and reset it when I got home.
Wind on a few weeks and the engine light came back on and gave me a camshaft position sensor error p0016 so I sent the car to my local Porsche mechanic who changed out the sensor and did a full service on the car including plugs filter oil etc etc. All this time the car has been running fine but as I wanted the sensor light out it was changed. However after changing it out the light came back on almost straight away. The car has been a bit sluggish to start sometimes and sometimes on pulling away from a stop has also been hesitant.
This was about 3-4 weeks ago and now it is worse again, at tickover it’s noisy, it doesn’t like acceleration and is running really rough although if you are going over 50mph it doesn’t have a problem and seems to run fine. The EML is now flashing rather than being a solid light. I attach a video of it running.
Any thoughts would be a help before I decide to get it hauled back across again

Recently had my air oil seperator replaced. At start ran a little rough now runs super rough and wants to stall. Changed 2 pre cat o2 sensors and mass air flow sensor. These are the current codes, 0112, 0300, 0301, 0302, 0303, 1316, 0102, 0130. Prior the car ran perfect and I cant believe I have all those cylinders misfiring because of plugs or coils. Please help

Unfortunately, I am back with another problem or problems........
A couple of days ago a check engine light popped up on my 997.2s and because it is my daily driver, I was not able to immediately diagnose the issue. I went ahead and ordered a "Carsoft POR II" scanner off amazon as i thought it would help my understanding in what the problem was. (Getting to the point.....) Today while I was driving home from class, the car was running very rough. I decided to pull over and give the scanner a go...

About 2 months ago I installed a new O2 sensor bank 1 sensor. While at it, I had a new AOS installed as well ( OEM parts). There are some theories I have in mind but as for now, I am truly stumped on this issue. Does anyone have any experience with this madness?! Thanks for reading! ?
This morning I started my car again and a puff of white smoke shot out of the tail pipes. The smoke did clear up really quick.
MORE NEW CODES;

MY2000 C2 Tiptronic Cabriolet, stock intake, around 70k miles.
I changed out the coolant tank about two weeks ago. During the tank install, I broke the oil filler tube. I wrapped it tightly with Gorilla tape as a few people had mentioned that as a temporary fix. I've driven the car about 250 miles since then with no issues. I detect a bit of gasoline smell in the exhaust but I'm not sure if it's my imagination since I had to disconnect the fuel lines during the tank R&R and I'm a bit paranoid after I work on my car. There are no black deposits on or near the tailpipes. Yesterday I was driving and was very low on fuel. I noticed a slight shudder every 15 or 20 seconds while I was idling at a traffic light. I filled it up as I thought maybe that was causing the shudder.
When I got home, I cleaned the MAF with MAF Cleaner. I started the car briefly and it seemed fine.
Today I pulled the car out and it was running rough immediately . Within about a minute I got a CEL P0301 - Cylinder 1 Misfire. It didn't rain yesterday but the humidity was close to 90%
I had changed out the spark plugs about 20,000 miles ago but didn't replace the coils at that time, which I assume were original. I just ordered new plugs and coils and will install them when they arrive.
Would a bad MAF or leaking oil filler tube trigger a misfire on just one cylinder?
I was planning on delaying the oil filler tube replacement to next year when I'll have my Indy replace the 7 year old LNE IMS and the AOS.
Is there anything I can check in the meantime?
2007 997 was running rough. The Durametric said misfire cylinder one. Checked the forums and saw most likely culprit was either bad spark plug, bad ignition coil, or both. Oreilly’s had the Bosch spark plug and a coul that was labeled Import Direct. For the sake of convenience I bought the plug and coil from them. The coil was actually the newer version Beru ( oem) with the longer bolts. Much easier job than I ever imagined. There are good tutorials on YouTube. Engine runs great and I cleared the codes. No check engine light and codes haven’t returned.
