Toyota Repair: 87 toyo 4runner EFI SR5 AT 4x4, questioneers, plug holes

Question
Hey Mike thanks in advance.  First appreciate your time helping all
the questioneers out in answering our questions. THANK YOU.  I
just bought the 4runner from a good friend of mine(not running). It
has been sitting for about 3 years and I know that 3 years ago it
was running and he just parked it.  What else could I do to be
proactive (i.e. plugs,wires,fuel,etc...)to make sure that after i charge
the battery, and change oil, I have better chances of it starting.

Answer
Poor some Marvel Mystery Oil in the plug holes. several ounces each.Then crank over the engine without starting. (disconnect dist.)then let sit overnight.then crank over again to blow the extra oil out before putting the plugs back in.
That way the rings will be good and wet and reduce the chance of scoring the cylinders from any rust that may have set in.
Change the oil,

add some fuel cleaner if theres old gas in her and have at it

Mike
