Good morning, 
 
Background: 
 Car has been sitting on a driveway and not being used very much over the last 5 months. (has been started every other day and left running for 30 mins or so.) I servicedit on Saturday (plugs,oil and filters (not fuel) 
 
I have now started driving the car and when i pull up to a junction/lights etc the car feels like it wants to stall and has started to self rev very slightly - however it never stalls. 
 
Any ideas?

                        If it was okay before it was put into a period of disuse, it could just be something like the warmup regulator sticking.  However no fresh petrol for 5 months isn't a great situation either.  If it was me, I wouldn't start tinkering with anything until I'd had a tank of fresh fuel, and a decent road trip with some high speed/high revs work included.
