The colour of the injector does not tell you what they are. They should have numbers on them. You're looking for a part number with either 355 or 803 in (these 2 are typical cossie injectors, and both are green). As said, 355s usually run with a 2 bar map sensor, 803s a 3 bar sensor.

The map sensor you've removed is not a Weber-Marelli sensor. Its output voltage may not conform to what the ECU has been set up for, so may cause running issues. Don't waste any money buying bits trying to get the car to run nicely on a chip you don't know the spec of. Either buy another chip and the associated parts and when it's running get it checked over, or get the car to a tuner.
