Problems in reading Air/Fuel Ratio Meter.

[Noel]

I got a Autometer Air/Fuel Ratio Meter in my tib and I dont know how to read it. the light is jumping from the middle into the "RICH" side all time at idle. Every time that I touch the gas pedal the little light go to the RICH point. I got a B&M fuel pressure regulator tuned with 45 PSI. My Chiltons Hyundai Cars Repair Book said that my engine has 43 PSI in his stock form.<img src=icon_smile_question.gif border=0 align=middle>

just from other posts that I have read, that seems to be normal... don't ask me why<img src=icon_smile_question.gif border=0 align=middle>

your meter is fine, you cant read air/fuel mixture when the car is at idle b/c there is no air/fuel mixing.

mine does the same thats normal. It changes rapidly because the computer is constantly changing the mixture, and when you give it gas it should go to rich because the computer is dumping fuel into the system. It's all running perfect. also I don't know about that fuel pressure number I run the zex nitrous kit and they say you need between 60 and 70 psi. my car runs great and the zex system automatically boost the pressure through the regulator, so it must handel it.<img src=icon_smile.gif border=0 align=middle>
