I have a 99 ram 1500 5.9 with 91000 miles and have an odd, kind of faint clicking noise(not constant) coming from under the dash(drivers side) while driving. I recently replaced plugs, wires, cap and rotor and dont remember hearing before that. Dont know if this is just a coincidence or if it has somethign to do with it. Any help greatly appreciated.
Since you just changed the plugs and wires check and make sure you don't have a plug wire shorting out on a place where the wires touch the engine or firewall. A shorted wire sounds like a click from inside the vehicle.
