What is the likely cause for"check injection" warning on Renault Megane 2.?

-The service light also comes on. it is an intermittent fault. had it checked on computer to no avail. the warning was showing when it was checked. It is accompanied with sudden reving upIf it is a diesel, the "check injection" warning normally signifies a fault with the combustion chamber pre-heaters (also known as glow plugs). It happened twice on my 2003 1.9dCi over the 100,000 miles I had it for.

I have no knowledge of the petrol versions.
sudden revving and then dying can be an air leak, check all your pipes and connections.
