Went into the shop today to chat, and they were super. I was getting ready to pull out of the lot after talking to the front desk and the mechanic actually ran out to wave me down to be sure I could understand what took so long.
We talked about everything he had gone over, which was a lot more than the front desk guy could relay.
Car is running very rich, O2 sensors reading .7 volts on both banks and he can't figure out what's going on with it. He double checked the manifold or membrane in the new fuel regulator as well as the vacuum line going to it, and it's fine. He did more but I don't remember specifics.
He's going to do a fuel sample and get back to me and check fuel pressure and I think the pump.
We talked about the wear pads and he said it could be something to replace later, but it's not what's causing this problem, and he brought up that Porsche doesn't mark them out of spec until -9, which is when the car throws a code. He's pretty stumped as nothing is throwing a code, even when he ran it without a MAF before replacing the MAF. Not charging me, he had a spare laying around.
Well I gave him a stock airbox and he'll be putting that on, which will help with temperature performance in the future. Again not what's causing the problem, as even with the engine cover off, it still stalls, I just wanted to put that back to stock.

I'm stumped, but at least now I'm sure he's working on it. Sounds like an electrical gremlin or a bad computer if nothings throwing a code like it's supposed to. I'm not sure.
