As you know, the plugs are difficult to get at (I always have to take a few deep breaths before tackling the job). So my point is to give you the best chance of moving them, make sure you have the correct quality tools. Quality spark plug socket, the correct length extension, and quality ratchet spanner.
With the correct tools so you can nice straight decent leverage I'd be confident you can move the suckers. Over 50 years in the trade and not had one beat me yet. Main problem is people do em up way too tight, just 'nip' tight is all that's necessary. They are spark plugs, not sump plugs.
Good Luck.
P.S. I agree with all the other posts. Replace the leads, plugs, fuel filter (buy the tool from Repco), and air filter. Only them start looking for what may be wrong if the problem persists.
