[DML] Re: Tune-up

---- The whitish stuff points to corrosion, which could be caused by water. Water is vaporized when the engine heats up.

---- Plugs can go bad. I had a new Bosch going bad on me (spark spit sideways from electrode to ground, right through the insulating ceramic.

I don't see a need to replace the plugs unless anyone suspects they are definitely the culprit but since I've only just began having troubles I am going to wait and try a few more things prior to replacing the plugs. 
> I have not cleaned ANY of the connections in the engine compartment including the resistor or all of the connections by the coil. I will try to clean those connections as well as the ground strap to the engine and see what happens. Then I will get a new cap+rotor and probably the coil as well. I had a 1950 Buick that was sitting since the 70's; I changed the oil and fuel, cleaned out the fuel lines/filter and it fired right up with the original 6 volt coil from 1949. I'm not sure how much the coils deteriorate over the years so I doubt the coil is bad on my car.

I am half tempted to grab a battery cable and install it from the bolt holding the ground to frame-to the engine block.
