Fuel injector testing?
Discussion
I'd like to get my fuel injectors tested as I've been chasing a misfire and have ruled out spark as being the issue, have replaced plugs (previous plugs all visually looked fine and identical), replaced HT leads and swapped a new coil pack through each cylinder, none of which made a difference.
I'm not getting any fault codes from the diagnostics (with EFI Live, not just a generic OBD2 scanner) so don't have a cylinder to focus on, have verified resistance across all of the injectors, so figure the next cheapest thing to try is having the injectors tested. A replacement is only £30 but swapping one of those through the system would be such a messy process with fuel everywhere I'd rather just pull them all out and get them tested definitively.
Anyway, I work in Aylesbury but live in Northampton, any recommendations on somewhere I can take a set to be tested?
Googling turns up a lot of diesel specialists, I'd be inclined to assume they could do the job but thought I'd quickly check on here in case anyone has a recommendation?

Marlin Motors in Bletchley can do it.
Before you do that I would get a temperature probe and see if you can identify which cylinder. Just measure the temp of each (cold) exhaust as it exits the head & see which one is markedly different as the engine warms up. Personally I'd be popping the cam covers off & looking for a broken valve spring.

That's an interesting idea, will see if a friend has a temp probe to hand Before you do that I would get a temperature probe and see if you can identify which cylinder.

I've already had the rocker covers off (pushrod motor) and didn't notice anything broken, but then I wasn't specifically looking at the valvesprings at that time, was just swapping back to stock covers to use the stock coil location and stock HT leads to eliminate the ones I made up myself!
Thanks for the heads up regarding MM too

These guys are in Aylesbury, but diesels, they may know who to speak to with respect to petrol injection.
I’ve got a temperature scope thingy to see which cylinder isn’t helping things along. Just call in one evening.
