2010 Spark Plug Cap Resistance

5 posts in this topic

I may have said that worng. I am looking for what the resistance of the resistor inside of the spark plug cap should be.

Ah, that's right, the '10+ models went back to a separated coil set up. That should be listed in the manual if there is one, but there isn't any indication that there is. Since no value is given, I would assume it is simply a solid conductive terminal. There isn't a need for resistance at that point in any case when the correct resistor plug is used. The plug cable is another matter, and might be either solid wire or a resistor type.

I could not find it anywhere in the manual. There is a resistor is there and it tested at 10k ohm resistance. I have a sort of intermittent "rough" sort of a misfire at idle. It kind of comes and goes. Someone told me they heard of those resistors having high resistance in them causing that kind of concern and that the resistor should be a 5k ohm resistor.
