This is on the Kia 2.4L, it’s the main front o2 sensor the $300 one that controls the a/f and all that.
And honestly this may not even be an issue it’s just something I observe and it might just be the nature of drive-by wire.
So the throttle response I think it’s very nice…. after adjusting the TPS sensor on the pedal, it’s precise, pretty instantaneous… no real delay, I don’t have a bad thing to say about it BUT…..
Let’s say I’m in third gear , and I pull from a off ramp up to Thruway speeds, There is a noticeable increase in power from 80% to wot. It literally feels like a switch… or Honda vtech And I’m just wondering if the front 02 sensor is getting lazy for the first 80% of the throttle and not reacting quick enough to throttle inputs, then when at wot it’s ignored? I don’t know this is just speculation and what it feels like the car is doing.
Gas mileage seems acceptable for the driving conditions. Every start up a one to two minute warm-up, well because I don’t need to say more.
Gas mileage can range from low 20s exercising the RPMs and shifting frequently, to high 30s on the highway with no AC.
I very rarely go wot, but when I do… I notice this.
So what do you guys think? Thanks.
EDIT: I do have an OBD computer with live data, graphs and other information that I could use to maybe read the readings of the sensors if I knew how to decipher the reading, so if someone could just give me a baseline on what data I should be looking at and what the numbers may be should be on average or what variations I should be looking for etc..
