so we changed 3 of the 4 plugs, the boot on the 4th plus came off and is now wrapped around the plug. Car still putts when it gets warm. I think its the coil. anything I need to know about changing the coil on this car?? I have never changed a coil on any car. I have basic mechanical knowledge but Im no mechanic. any tips, tricks or ideas would be helpful. We also plan to replace the wires and cap.
