94 honda vx with c1 swap , i just recently installed an air/fuel ratio gauge. i had a shop do it for me. but for some reason the gauge is stuck on green.! im guessen it's stuck on burning rich! cause my exhaust fumes are black when i shift and when i normally drive..! where is the air/fuel ratio gauge suppose to be spliced into.?

 

white wire on o2 sensor

 

im goin to guess ur OBD2, which would be the all white wire...

 

nope it's an obd1 they said they spliced into everywire in the o2 sensor and my gauge is still hitten the green. it doesnt move when i drive or at idle it just stays green..

 

if its staying on green all the time i don't think you hit the right wire, it supposed to be the white wire on the o2, and if you did put it on the white wire, sometimes it takes a little while to heat up the o2 sensor to properly work on the gauge

 

it should go full lean on decel

 

check the article on teamintegra.net for the OBD1 version of the install, i think its the white/red wire..

 

could it be that the o2 sensor is bad ? and the gauge stays green ALL the time never changes...

 

what type of gauge is it, autometer?, I wouldnt trust anything except fjo wideband sending unit and o2 sensor. the vx's have the 5 wire right? if so, thats the one i run with my fjo. My autometer a/f gauge always showed me rich while in boost and when i put it on the dyno and used a wideband i was dead lean and i was using a brand new o2 sensor right from honda with the a/f gauge. just my $.02. find someoe locally with a wideband and pull some street runs to actually see where you are at.
