Actually I am slowly learning stuff. I just read my codes using a code reader:

From Peake Research R5 code reader Table 22 :-
278d - Temp sensor coolant temp
274e - Misfire detection checksum failure
2748 - Misfire detection cylinder 7
2749 - Misfire detection cylinder 2

coupled with the symptoms right now:
a. Rough idle, rough running at certain speeds / times. Engine switch off/on again usually helps to smoothen it a bit but not completely
b. Oil leak (requiring stripping engine down, say BMW)
c. Slow coolant leak apparently, (from inside engine say BMW)

Next steps anyone, which a newbie like me might be able to perform?
