Loss of power above 2000 rpm on Grand Cherokee 2.5 TD '97

I am posting this just as a reference to anyone who experiences the same problem.

Cause:
Took the Jeep to get the engine washed. Since then the power gets cut off as soon as the engine reaches 2000rpm. Feels like I have released the gas pedal. The fuel consumption goes down as well.

Problem:
Apparently the jet wash has damaged the sensor of the No.1 injector.

Solution:
Bought a second hand one from a scrap yard and replaced it. I needed a special 28 socket which I bought on the internet for 8 and I had to file a bit in order to fit. Also I had to cut the wires as the connector didnt fit (likely the injector was taken from a slightly different jeep than mine).

Took me 20 min altogether to complete the job and the jeep is now back to normal.

Hope this is helpful to anyone else.
