I have a 90 Crx B16 Non OBD. It is running rich as hell. I have checked the fuel pressure and it is fine. I have replaced plugs, wires, cap, rotor, fuel filter, O2 sensors, and the map sensor. I have already made sure that I wired the O2 sensors right. There is no check engine light. I don't think that it could be a leaking injector because all 4 plugs have massive carbon build up. I was wondering if anyone could tell me what the voltage coming off the O2 sensors should be at idle, and also the voltage for the map and tps, or any kind of suggestions. Thanks for any help.

 

Does anybody know where I might be able to find this info since no one seems to know it?

 

what ecu are running?

tps should be .5 closed and 4.5 at WOT

 

I already found the map voltage and tps. I am really looking to find some info on the O2 sensors. I know they range from 0 to 1 volts, but I am trying to figure out how many volts it should be at idle. And which way is lean and which is rich, like 0=rich and 1=lean or the other way around.

 

Bump for some help...

timing retard or advance could help it...

 

The timing is set like it is suppose to be. Any other suggestions???

0 would be lean and towards 1 is rich. However, the O2 voltage should not stay steady, but if you are running terribly rich, yours might. I dont think looking at O2 voltage is going to do much, since you already know you're rich.

Why dont u tell us your findings to make sure you're on the right track. For example, what was your fuel psi? What did u set the timing to? Maybe a pic of your vacuum line routing would also help.
