Video of my 1.8 dying...Can anybody guess why?, Looks like it was a poorly connected double relay!!! Options

Update: No new engine for me right now, the 1.8 is once again running strong. Thanks everybody for looking at my videos and posting in this thread.

Edit: I added some video of my 1.8 engine's behavior. What you are seeing is about 2 minutes into the engine running from a cold start. I tried to capture a little of the shakiness of the engine as well. Wondering if anybody has a good idea of what's going on as I may want to sell the engine after the swap.

914 1.8 Stalling

Original Post:

So late last "season" (Porsche weather is May to November here in Michigan), my car stalled between shifts. Started up OK but conked out when warm. So...I discovered a disconnected hose and started a hose renewal project. After replacing every hose, the problem persisted. But along the way I had to replace the AFM as the car backfired and warped the flapping door. Still no success. Replaced the fuel injection seals, oil filler cap seals, still conks out after warm up. Contemplated a new brain and wiring harness and cylinder head temp sensor but have run out of patience.

To make a long story short, I've decided to go with a 2.0 and plan on dropping my car off at Brad Mayeur's next weekend. I've always wanted more power anyway.

Questions:

1. How much power am I losing by sticking with the stock 1974 exhaust system?

2. What to do with the 1.8? It ran strong before the problems developed, but the car is of unknown mileage. Seems like interest in these engines is, well, underwhelming. Brad said he has more than enough of these engines.

3. I'm sure he could get the 1.8 FI running on the 2.0, I know there are proponents of the L-Jet...Is that something worth pursuing or stick with the D-Jet?

Thanks,

Paul

BTW, I have a pristine orange 1.8 that is staying stock. This is for my red driver!
