TFI Coil supposed to make noise?
I Just performed the TR ignition upgrade. all went well, except for one problem. well, its not really a problem. I mounted the Filko TFI coil to my firewall (which is fiberglass) and when the engine is running, the coil makes a funny, annoying rattle noise that can be heard very well in the cab. It sounds just like when there is a leaf in the way of the heater blower motor (i know it is not this, b/c the heat is off). i was just curious, is this normal? I have headers with glass packs and you can hear the noise over the exhaust with the hood open. i cant imagine a stock, quiet ford taurus with a coil rattling away like this. maybe it is just the fiberglass resonating the sound. what do you all think?
