I own a 95 bird. I understand this generation of the t-bird is rather notorious for having problems with spark plug wiring. I recently had a problem with the car "shuddering" and it was due to a plug misfire. I replaced the plug wires with some "premium" insanley expensive ones from advanced auto, also replaced the spark plugs, also insanley expensive ones. Car ran great for about 3 months I suppose. Now it is slowly starting to do it again. There must be a reason why, could this be the coil packs needing replacing, and if so, after they are replaced will the plug wires and plugs also need to be replaced?
Thanks for the help
