I have a 98 Ram 1500 4x4, 5.9L auto trans, 92K miles. I installed a new Mopar Dist cap, rotor and plug wires and new autolite (not platinum) plugs. and now have a miss. It is throwing P0308 (8the cyclinder misfire) put in another new plug and put the old wire back on and still have a miss with P0308 code. Any ideas, Coil? What next.... Thank you, James
