Engine idle is very rough and it lopes and sometimes it cuts out. I've replaced the plugs and wires and it still idles like crap . I connected a timing light to #1 cylinder and found that the spark cuts out and is the same for all the other cylinders when I checked them the same way. When I drive on the highway there are no problems it seems to run fine,but around town its a little rough. Could it be the coil pack or ignition module.....please help !!
