The engine uses mechanical fuel injection similar to a lot of VW, Audi,Volvo and Peugeots. The system is sensitive to water contamination, but see if there is any independent European car specialist that has experience in older European cars. It could be the cold start enrichment. but you need a special fuel pressure gauge set up to measure system pressure.
Look up "Bosch K Jetronic" you will find over view of how the system.
