futura 3 Posted September 27, 2006 Since trying on a different set of injectors sorted my warm starting issues, I concluded that my injectors were leaking. Phoned up ASNU to ask if the replacement of micro filters and seals would sort the leaking and they said it probably would. So I sent them my injectors and drove the car with the spare set, which was making it run rough and with a loss of power. Now I received the injectors cleaned and refurb'd, but the report says they did not leak to start with Only fitted them tonight so need to wait and see if the starting problems are still there. I don't understand what injector fault other than leaking would cause warm starting problems??? Also I thought the flow rate of 1.9L injectors was 214cc per injector - or is it for the four injectors all together? My report says that each injectors' flow rate is 54cc ?? Please educate me!

TEKNOPUG 3 Posted September 27, 2006 They may not be leaking but they could have been blocked or partially blocked leading to an inefficient spray pattern? Or though they look fine pre-clean from your print out..... Share this post Link to post Share on other sites
welshpug 1,657 Posted September 27, 2006 stick em in and have a drive, shouldnt take more than 10 minutes to fit Share this post Link to post Share on other sites
futura 3 Posted September 27, 2006 (edited) They were on 5 minutes after I checked the post lol But haven;t had the chance to drive enough, stop and start the engine from warm yet. So far smooth idle, a bit rich and had to re-adjust it too. Started fine too. Edited September 27, 2006 by futura Share this post Link to post Share on other sites

My report says that each injectors' flow rate is 54cc ?? erm yes 214cc would be for all 4. Need ~170 bhp per cylinder do you ? Share this post Link to post Share on other sites
futura 3 Posted September 27, 2006 Ok I understood the report: the official flow rate figure of 214cc is given per minute. ASNU's test lasts for 30s with a 50% duty cycle, which means that overall one injector is in open position for 50% of the testing time, in other words 15s. 15 seconds being a 1/4 of a minute, the figure of 54cc per 15s makes total sense, as it means that the injector's rate per minute is 216cc I still don't get how they put that my injectors were not leaking though Share this post Link to post Share on other sites
