Injector Duration - misfire

Injector Duration - misfire
I've had a misfire for quite a while, that I've been living with in my MY00 Turbo. I can be at a constant 1750rpm at 30mph, and the injector duration is around 4.5 odd milliseconds. I notice it then drops to 0.51 ms, or perhaps that's just the lowest reading my data monitor shows, but it obviously is a noticeable difference.
Could it be the 22 year old injectors? Things I have changed, leads, plugs, MAF, fuel filter and fuel pump and sock. I've swapped the coil pack over as I have 3 of them, all of similar age, that didn't make a difference. I will also have access to another 2 sets of injectors, of a similar age too. Should I swap them out, or should I get a set cleaned/flow tested and put them in?

I had a misfire on a 80k mile blob some years ago, and was assured by 2 "experts" that it was highly unlikely to be injectors, so I replaced just about everything else to no avail. Finally I had the injectors cleaned by Injector Tune in Wiltshire and it was like a new car, gaining considerable power as well.
Injectors are rarely considered for maintenance, but fuel cannot ignite optimally without correct spray patterns

have "solved" many Gen4 JDM Legacy issues over the years by cleaning their injector set-up so it certainly does and can have an impact as above.....

Thanks all.
I will check the neutral position switch too.
With regards to the injectors, should I try something like redex for a bit, or just get the cleaned properly? I rally don't do too many miles either way. So I suspect the redex option could take a while to get through

any of the tank additives whilst being partially successful to some degree can never achieve the results of a proper testing / cleaning regime
it also won't tell you if you have a 'faulty' unit and more importantly that it has been resolved

found these guys to be good value, £15 an injector. Just as important a service as your spark plugs!
