ok what's up guys i am kind of new to this massage bord so i did not know where to post this so if i posted it in the wrong place i am sorry but i know you NOS guy have Air Fuel Ratio Gauge. so hear is my question i am going to get a Air Fuel Ratio Gauge because i just started running NOS right but the Air Fuel Ratio Gauge works with a oxygen sensors but dose a 98 RS have a oxygen sensors or do i need to get one help and if i do how much are oxygen sensors.

yea man. all eclipses have o2 sensors. pop your hood and follow your exhaust down pipe and on the left hand side, youll see a little bolt lookin think with (4 i believe) wires commin out of it. you have one there and another behind your cat. the front one is used to make changes and is directly linked to your computer and all for making adjustments. your rear o2 sensor is just there to check and make sure your cat it workgin ok. youll attatch your a/f guage to the upper sensor (the one you can reach from your engine bay. dont ask me how to hook it up tho, cuz i have no clue in hell! lol, but yea, all cars come with em. find somebody who has hooked theirs up, or try a search for a/f guage install. hope this helps!

the singal wire that u should hook up ur a/f gauge is the white w/black line follow ur oxygen sensor wires until u see the white/black wire . ur readings are only going to be at wot (wide open throttle)

why is it that the readings are only going to be at wot (wide open throttle)??
