Cayc injectors.

[nevo]

Hi,all having trouble with the wifes golf cayc 1.6,she's knocking at gentle revs (the car) then sometimes it will have a fluctuating idle then start bucking a bit misfiring putting out some smoke,checked the inj deviations and there seems to be some wide aviation at 1200 rpm,when its running with just the diesel knock if I boot it it will pull fine any suggestions.20230605_120714.jpg

You have two going there, you had better hurry as ECP are down to their last 4643...

Thanks for the reply you reckon 2& 3 or are the way out,noticed no 4 wasn't coded in,changed it to the right code and that seemed to make it worse so put it back to original,its running just knock at low revs about 1200 rpm,do you think a inj balance would help,also whats the recommendation on inj genuine/aftermarket or refurb.

Update for anyone interested,re-coded the 4 th injector and run a minimum deviation program and its running fine now.
