Had a cel light on...was throwing o2 sensor heater code so I replaced my primary o2 sensor now have an issue with my car bogging at low rpm only in first and second...under harder acceleration there is no bog...if I unplug my o2 sensor the cel comes back on and it runs fine...I know the primary o2 runs in closed loop so its prob the o2 causing the prob ...but I'm a lil confused as to why this is happening...anyone have any info

 

Did you reset the ECU?

 

I cleared all codes...reset the Ecu..its so strange...I've done b swaps in my civics obd2 to obd1 conversions but never.ran into something so obsurd...all codes cleared no cel and it bogs...unplug the o2...cel comes back on and it runs fine...can't figure.this out for the life of me

 

Really driving me nuts!
