Hesitation on accelerator and low power

Hi Ken. I want to thank you for your replies and expertise so far.

Thanks for the windshield advice, noticed some areas where water definitely seeps in. Will sort that soon.

Please shed further light on me with some new problems that arised after the car came back from electrician.

So remember the problem it initially had before going there? (No starting, erratic idle, switching off. Also accelerator pedal did not respond). Changed the blown control module and that sorted out starting and idling problem. It now has no power, when I drive in low revs it hesitates very much unless I rev a bit harder. On higher revs and faster speeds it still does not feel normal but the car moves okay. I changed plug leads last night, took it for a test and still hesitates a lot at take off?

Furthermore, I noticed a water leak coming from something that sits just behind the thingy that the plug leads come out of? I do not know if that is the coil? But the leaking thing is behind what I think is the coil. (Video attached) Please tell me what this is called and how the leak can be fixed?

This trial and error is draining the pocket but I guess there is no other way.

Look forward to hearing from you again.
