i have just done this test, the method i used was....idle for 2 mins, 3k revs for 30 secs, idle for 30 secs, 3k for 30 secs, idle for 30 secs, 3k for 30 secs, idle for 30 secs. 5 mins total.
results
1. 70ml
2. 57ml
3. 60ml
4 60ml
whats the verdict on these results, for information, car runs ok 95% of the time and has hesitation at other times, 1st start up in the morning i need to press the accelerator further than you normally would, to make sure it starts. rest of day it starts fine, i am currently doing around 700 miles a week mostly town driving. there was one occasion where it didnt start first time and threw the code injection pump control A, i cleared it and it has never come back over 3 weeks.

 

Taking a punt that it's a Mk3 Mondeo - Those figures are about right, although the test should be done at idle IIRC. Unless it's not a Mondeo?? The important thing being that one isn't miles out. The cost of replacing them will probably outweigh the cost of the car, so I'd leave well alone. If it's runs ok 95% of the time I'd be grateful... But as soon as it starts to cause grief get rid! I speak from personal experience!!

 

sorry, i should have said, its a 2004 1.8 tdci focus 115bhp, injector 1 that is the worst, maybe its only just going to get worse? i need for work and i was going to be a reconditioned one and fit myself...if this is what is causing the hesitation? EGR is blanked off, no air leaks.

 

 

obviously the empty bottle is not part of the test.

 

Does anyone have any opinions on this result. Does injector 1 need replacing. I just showed a mechanic the picture and he says they all need replacing looking at that! For information, the highest reading is more than 10% difference than the lowest.
