O2 voltage 0.2 / bogging throttle blip

Post by MarkyMark203 »

K24 EG civic
Kpro v2 newest software
K20a2 harness
HR conversion harness

Car had no codes. If I blip the throttle quick it dies. If I slightly rev it revs. Idle won't follow in kpro and I noticed the o2 sensor voltage is around 0.2 or so. Is that normal? Could a bad o2 cause this?

Your idle is high, and the TPS when idling does not ever go to 0. Make sure the MAP and TPS sensors are not switched. Try calibrating the TPS and setting idle properly as well. If this has not yet been tuned that could also be the issue.

The idle is from the idle adjustment screw as I had to adjust it to stay idling, maybe that's why its not at 0%.

I did calibrate the TPS and it rolls buttery smooth.

Im just worried about the o2 sensor voltage, is being that low normal? Im going to get tuned tonight so well be using his wideband from the dyno, hopefully it reads correctly. That way I can still tune it and then just worry about the lean issue later on my own.
