Is it possible for my 1988 Ford Bronco to jump timing during use? The idle is all over the place. During initial start-up it's around 7-800. After driving for awhile it gets faster. After freeway driving it's around 1400. Also have an annoying pinging at accerlation. Tried better gas, plugs and wires, cap and rotor. Still there. People i've talked to say the pinging could be from timing being too advanced. Plan on getting idle control valve this weekend, but I don't think that will help with the pinging.
