Sapper 157 Posted September 17, 2015 Share Posted September 17, 2015 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?

DaveT Posted September 17, 2015 Share Posted September 17, 2015 Bad wires usually make rough rumning. Get a set of NGK wires. Last forever. 1 Link to comment Share on other sites More sharing options...
