Too few symptoms to identify a problem.
But if you are in halfords get a bottle of petrol injector cleaner, Redex and add what it says on the bottle (or less) when you top up with petrol, you only need to do this until the bottle is used up.
The car not being used for 6 months may tend to annoy the petrol injector, petrol is volatile but leaves a gum residue behind when it evaporates.
Do have it serviced regular, they are resonably reliable given some attention.
