Anyways I keep getting this stupid 0300 Multiple Cylinder Missfire code! I have changed out both o2 sensors, put in the mil eliminator (wich made the emission code go away), I changed plugs, wires, coils, battery, checked all vaccums (however it is spelled), and well now I'm completely stumped... I have a very hard time beleiving it has anything to do with fuel... Does anyone have any advice or experience with this problem? Thanx you guys!
