[QUOTE="ALBundy, post: 45428, member: 15"] For the coils, you cant tell whether they are working or not just by looking at them. I have had similar experience before, a perfectly looking coil but it was faulty! maybe you should swap the coil from cylinder no2 first. How there is oil? Is the valve cover gasket leaking? I am referring to the gasket that protects oil from going into the spark plug (rubber gasket with three holes, 2 pieces for 6 cylinders). If there is a bad leak, will also cause it to misfire. Now since you have removed it, swap the coils and start the car. The procedure is to remove the coil when the engine is running, one by one. IF the coil is working, when you pull it the socket (the one that connects to the coil) it should misfire! When you repeat the process and it doesnt misfire then that should be the faulty coil! *disclaimer* If your car is screwed I am not liable :lol: :lol: [/QUOTE]
