Could you tell me if  "There is some trouble with my car engine" ---1is right?

Or 
     There are some troubles with my car engine.----2

Answer

'There is some trouble' is better if you are talking about a technical or mechanical problem.  'Trouble' is usually uncountable. If you say 'troubles' it suggests personal difficulties in your life.

Answer

Both sound rather incorrect in English. I would say, "I'm having trouble with my car's engine." or "I'm having engine trouble."
