Brand new to 914’s and I have a 74 2.0 FI. Car died at 70 mph in 5th gear going up an incline. Wouldn’t restart. Towed the car home and a few hours later it fired but was running rough. Pulled the plugs and cylinder one was soaked in gas. Does not appear to be any fuel in the oil. Head temp sensor was replaced in July, along with distributor and points. I believe the engine stall at 70 was from being flooded but idk where to start. I also disconnected the 5th injector to make sure it wasn’t stuck open and causing issues. Any ideas would be greatly appreciated. Thanks in advance.
