Faulty Injector light but only sometimes

[needy]

Hi All

The wife got a 1.9d 2005 that drives fine when she drives it

BUT

When I drive it and gives it some stick to give it a clear out the faulty injector light comes on and have a slight lack of power but when I pull over turn engine off then restart its fine again until you give it a bit of stick again

Any ideas what this could be

Thanks

try looking through some of the other threads to see if you can puzzle it down to a solution
9 out of 10 diesel owners on here, including me, will have had this fault come up so there should be plenty of info about
