Bet it ain't injectors. Don't guess, Wait till you get the reader. My guess is that it's running fine, just an annoying light on.
Ours used to pop up regularly "cat sensor 2" but only if I drove frugally between 40 & 60 for 10 mins or more.
 
What's the plugs look like ?, Compression test? Owned petrol Scenics for years, NEVER had a faulty injector. Try disconnecting one injector at a time to find which cylinder. Also clean TDC sensor. Do the cheapest, easiest things first.
HTH

Sometimes faults of certain types will clear after 5 Clean start / runs.
I prefer to read & reset. So I know it's cured.
