Recently bought a 90 gt and I'm having some issues with idle. It starts and will die sometimes, but coming to a stop it will do fine most of the time. I pulled the upper off and saw that the injectors are all different brands. Is there a way to check the size other than buying them yourself and just knowing what you ordered. I think I may be running alittle rich and maybe I have too big of injectors. Any help is greatly appreciated.
