I had some reconditioned injectors fitted this time last year and have done 25,000 miles and tonight on way to work my engine management light come I got a feeling its the injectors again as I have noticed the car to be sluggish and on tick over it ticks over but very lumpy like its going to cut out it did this last time too and when you accelerate the light comes on

What I'd like to know is what if any sort of warranty should I have there's nothing written on receipt I got and nothing on there website?

Off to bed now so will have to call them thus afternoon
