Advice Please for my hicuppy Freelander

Hi, my Freelander GS 1800 recently started a very interesting experiment with me! It starts fine, runs fine, but... when accelerating through 2k to 3k revs it starts a jerking motion like it is suffering from fuel starvation, but resumes normal running after 3k revs or less acceleration! Also had the three amigos on the dash, so got my brake light fixed and now when I brake the park light (i think it the park light light on the extreme right of the dash) comes on!?!?! All advice welcome!
