So I recently used the zmax fuel treatment and am still on the same gas i used it in. My hemi hesitates when I start it up when the engine is cold. Does anybody think the zmax may cause this and it might go away after it's all the way through? I recently installed a moroso catch can too but I checked the connections, nothing is kinked, and I emptied it. I was surprised how much was in there after 150 miles. Thanks for any suggestions.
