**I know I've gone over to the dark side :p lol but just posted this on the Jag forum so thought I'd better get it on here also... Might come in useful to someone sometime! :)**
Decided to have my injectors cleaned professionally and found a place fairly local (over in the Wirral) and had them done yesterday. Great guy - very down to earth and knew his stuff too. :)
Before I went down I took them off (as the Mrs was giving me a lift over there!) and numbered them up incase one performed particularly badly!

Initially he performed a leak test, which all the injectors passed. Following this a test for the spray pattern. All injectors looked pretty good but number six a little different from the rest.
Then for the intersting part which was the flow test! (Measuring how much fluid passed through each injector in a contunous 20 second burst (Under 2bar of pressure i think!). Here's how they faired:

Not bad at all really considering they have 136k miles on them :D The most important thing is they are around the same level - similar to a compression test.
Next he put them in the ultrasonic cleaner for three cycles (kinda like a jacuzzi for injectors that makes a rather annoying noise!)... Then he re-flow tested them to see any change.

The cleaning improved the spray pattern on #6 and increased the flow rate from around 65ml over a 20 second period to around 70ml! :D
Got them back in yesterday evening and took it for a drive (on a few errands!)... Car feels really good - Smooth as you like and I would most definitely say improved response on WOT :twisted:
All injectors tested/cleaned/re-tested for £60... Plus he changed all filters and o-rings. Bargain! If anyone wants contact details just let me know. :)
