Its a common source.
The thermo-time switch is used to regulate the cold start injector and limit the amount of fuel on a start. If its bad, it acts like its flooded. The switch on my 4.7 84 cars is located on the passenger side of the front of the engine. It looks like a temp sensor. Its top faces the front of the car, and it screws in towards the back of the car. I've replaced them on two USA 4.7 cars.
Fixed the issue on both.

Well, I have mechanical injection...its a 80' model. is your solution still relevant?
How can I test the cold start injector to check if it is ok?
