My 172 is due a service and is actually booked in for this thursday. I had it last March and havent had it serviced so far.
For the last week or so I have notiched some slight miss-fires in 3rd and 4th gears at around 3000 - 4000 revs.
I just wondered if it is because it is in need of sum new plugs etc. Oh, and the service light came on last friday for an hour or two, but has gone off again.
Can anyone shed some light on this?
