Hi,



I have been to 2 different smog inspection stations.



1.) First one pulled the RPM signal off the battery and said they couldn't get a good reading.



2.) Second station pulled RPM signal off the spark plug wire and said that when the fan kicked on, the idle RPM that they read went from 800 to 3300, even though it wasn't actually doing that.



I need to get this bad boy smogged any quick ideas/fixes?



Thanks,



Micah

plug wires maybe? or keep trying smog stations

how the hell do you get an rpm signal from the battery?



man the guys at inspection get smarter everyday.

With special sensors, there is a pulse in the electric system and can read the ignition pulses. The rotary has 2 different pulses for leading and trailing so it doesn't work well on our cars.



G-tech Pro I believe can do this.

put that in the category of things i didnt know.

Thanks for the input. And I wasn't sure how they did that either.
