How true and wise. For some reason I didn't really think of the misfiring too much cuz I got so used to it. But my heart ached whenever I hit the brakes and the suspension would moan like it's dying. Now is there a way to test each coil over for the spark plugs? Because there aren't any spark plug wires on our cars. That's the big thing. I need to figure out which cylinder is misfiring. Warranty? HA! I got almost 50k on my mustang already. A shame, isn't it? But it's going to slow down a lot now. So yeah, the warranty is most definitely up. Mods? Nothing really, just y2k chrome wheels, lowered fms springs, catback, off road h-pipe, and I got LTs and a bassani high - flow x pipe in my garage.
