well I've had an idle problem from some time now, happened right after I installed my rb downpipe, found an intake leak so I put my stock tid and air box back on, helped a little, after trying to tune the idle myself and with out luck I took it to my mechanic and he tweaked the idles as much as he could, now it idles strong but when it misses it just stumbles and wants to die. My mechanic diagnosed the problem as a sticking or leaking injector, my question is is there anything I can do to fix this problem with out buying new injectors? I have been using injector cleaner.........which injector(s) would be sticking -- primary correct? finally could I just upgrade my secondary injectors and use them as my primarys, or should I just go out and buy 4 new 850 cc injectors?
I have an S-afc installed to tune the injectors......any suggestions

 

You could get them overhauled and blueprinted for only $25 per injector. New gaskets and everything .. that should help fix the current ones with the least expense. There is alot of places online that do that sort of thing. I found a place local to me .. a deisel shop to do mine. But RC engeneering sp??comes to mind also.
