I?ve got a 2007 Town and Country , that started missing on one cylinder! So I order a new coil from Rick auto, put it on, Runs great, three days later it starts missing again! So I figure , the plugs have too wide of gap and burnt the new ( China ) coil out! So I order a new coil, ( it was a SMP coil) and a new set of wires and spark plugs! Well life happened and I let it set for several years, near caught it on fire, trying to start it. I get it in the shop, by putting the new coil and three spark plugs in it! I then replaces all plugs and wires, it still missing on one cylinder! Sitting in the car, the right front spark plugs has no spark! New coil, new wire, new plug! What should be my next step? Thanks in advance, Bones
