Evening what sort of mileage are you talking?
I suppose pulling one or two would show if they are dirty or worn but you'd need to inspect the tips very carefully. Are they nearly £50 a pop ?

If it isn’t broke etc etc, injectors will tested as part of their service and then ultrasonically cleaned and spray patterns checked.
Any of the injectors knocking thus indicating wear, if not and the engine running and idle is fine leave alone just stick a bottle of Redex or similar injector cleaner in the fuel tank and leave it at that.
Very good point..

Think outside, no box required.
I had mine cleaned last year (V8). I had a warm start issue, and a smelly exhaust. Having eliminated lots of other potential causes I bit the bullet and stripped out the injectors and sent them off. New o rings and filters, with a report on spray patterns. c£80 iirc - they will tell you if one is up the creek and needs replacing.

Lots of information if u Google ‘how to clean fuel injectors’ I’ve never had any injector issues, but it appears from my quick search the injector spray Is okay with just an even fan patten plus any cleaning can be done with carb cleaner.
Also instead of dismantling the fuel rail the injectors can be tested individually with a piece of electronic kit as shown. What ever next

Instead of reconditioning the originals I bought these https://www.ebay.com.au/itm/8-GENUI...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 Plug and play and a couple of questions I had the fellow was extremely helpful and came back with answers very quickly.

Can you not just pull it out and stick it in a cut off bottle or something and run the car briefly to check it is spraying evenly?
Misfire under high load: have you checked compression?
I cleaned mine on the bench.
- 12" Length of tube on injector inlet.
- Fill with carb cleaner.
- Far end of tube attached to compressor via regulator set to 20 PSI.
- Point injector outlet into a jar.
- Pulse the injector with 9V - 12V & see the dirt & crud come out.
- After a while you get a nice even spray.
- Fit new seals & re-fit to engine.
