5.2 magnum options

i've used the spray bottle trick reccomended by magnum mopar , on my car before and it works great , also try it when its dark out ,helps to see sparks, mine was two part problem spark plug wires that were grounding on headers,and the main plug on the motor that has the coil and ballast wires in ,a lot of the connections were corroded my misfires went away after repairs, good luck rule out wiring before mechanical.
