Ha ha. My naivety strikes again
Thanks very much for your frank reply.
Your description exactly describes what I expected initially; actually I never even gave it a thought. You live and learn.
I actually did do some reading on the subject after posting yesterday and realised the depth of the 'rabbit hole' after my oversimplification. As you say, pressure calibration and unification of all injectors etc etc.
I've put the old nozzles / needles back in and it runs better but, I'd obviously like to get this aspect perfect. I'm just glad the initial noise wasn't anything worse than this.
I think my choices are:
Buy a set of recon injectors, although I'm not sure if these will all be calibrated the same so they are all deliver exactly the same fuel at the same pressure? I'm looking at genuine Bosch recon items @ £45gbp each.
Do you think they would be?
Or
Get someone more competent than me (not too hard) to set the ones i have up properly.
I could do as you suggest; get a pop tester and shims but am unlikely to ever do this again and might waste more money on gauges and still not get it right.
I'll have to do some more digging I think.
Thanks again for the reply. It's good to be able to run my woes by you.
