So this is a question ive had many different answers from. I would like replies from only people who know what they should actually look like. Im running a obd1 GSR B18c JDM motor with a PR3 ecu, with many mods... including VAFC for some tuning. Im trying to dial in my fuel so im not running to lean, or overly rich. Mostly watching my plugs. Before I installed the VAFC my plugs were an off white. So running a touch lean. I installed my VAFC and added a bit more fuel on the rpms and now have them running a touch richer. Plugs are an off white, with a slight gold burn (very little). What exactly should the plugs look if im running just perfect. Thats the question im looking for. Thanks for the help!
