Be weary that not every car has this, it depends on what type of ignition your car has, mine does not have this resistor.

I'm not sure, but if someone can back me up on this, I think an easy way to tell if you have this resistor or not is by looking at your igitnion module, if there is only two connectors on it, you have what I have and you don't have the resistor, if you have four and a vacuum line, then you have it.

Other memebers also mentioned that this is not as good as it sounds, and not worth the gas money in the long run, I prefer to make sure that engine is well maintained instead.
