My car has been idling strangely lately, it will hover around 1000 rpms when warm, but it tends to go up and down erratically. I have cleaned the carburetor only heaven knows how many times, I have brand new fuel filters and an almost brand new fuel pump, so that should be good. My spark plug wire are aftermarket and the cheapest ones I could get and I'm thinking they are the problem. Because when I replaced my disty cap there was a ton of green bluish corrosion in one of the contacts that the spark plug goes into. that same spark plug wire has a little bit of corrosion on the diode that goes into the little contact. I tested the spark plug wire today with a digital multimeter and it came up as 6.40ish ohms (DMM was on the 20K ohms setting, so I guess that is 6400ish ohms right?) but when I moved the wire it would jump to 16.00 ohms. is this normal or do I have a defective wire? 

Bad wires usually make rough rumning. Get a set of NGK wires. Last forever.

Alright will do.
