I have a 1996 dodge 1500 with Magnum engine. Engine shakes while idling and shakes violently at 45 mph if slowily increasing speed but not when you seed up rapidly
try a tune up. plugs, wires, cap and rotor
Did plugs wires help? I know this is old thread but Im having same issue. Why shudder at only 45-55mph and not the whole drive range?
