i hooked up my A/F gauge my idiol went up and down and the car almost stalled and like half of the scectrom was lit up and then when it went lean it started acting up but soon as i disconected the sigle wire thecar went back to running fine

i have a 95 DX hatch with a b18c1 but it have a 96 gsr harness in it but i am useing a obd2-obd1 convertion harness and useing a obd1 P-72 ecu

i used the convertion harness becouse i was getting a cell from a secondary o2 being missing but now there is no cell with the obd1 ecu

the o2 came fom my turbo teg and i am useing the same A/F gauge and signal wire also and i also tried a diff A/F gauge and it does the same

 

anyone have any idieas?

 

i was thinking about a bad o2 but it worked fine before i took it out of my teg

 

Your gauge may be taking to much current from the O2 sensor and thus screws up the reading. You'll need some sort of of current buffer if you want to draw the signal from the 02 sensor the ecu is using otherwise run an O2 sensor dedicated to the gage.

 

but the thing is that the same sensor working in my teg and it is the same gauge would it be a bad ground on the o2 wires?

 

yeah, maybe check the ground strap on your head.

 

the ground strap to the head on top of the valve cover in front of the motor is there but i will take it off and clean it what wire on the o2 is ground maybe i and runa jumper wire from that wire to ground

would something like that work?

 

Is this a single wire o2?

 

it is a 4 wire o2 from my 95 integra gsr

 

Hmm. Not sure what to say but check it with another O2 sensor if you have one available.

 

i might just pick up a new o2 that is the only thing left thanks for your help though

 

does anyone one else have anything to add?
