Hi Community, since I had my Stinger (3.3 BJ 21) in January for a 2-year inspection (without oil change, i.e. on the engine was actually not done), I notice a strong stutter with large thrusters when accelerating from about half to 3/4 gas. With gentle driving the motor run is actually inconspicuous and also the consumption is in the normal range. Error codes are unfortunately not set, so that I am a bit helpless, which is the reason. I was therefore already with KIA, but their next appointment to look at the problem is unfortunately only at the end of March. The master suspects the usual suspects such as candles, ignition coils or injectors. Since I would not like to drive around for another month with (probably) ignition problems, I started looking for the cause myself. I looked with the iOS Car scanner in the signals for striking values, and at the same time the air flow rate (“MAF air flow”, see screenshots The first screenshot is at a constant 130km/h, and the second one is in idle mode. Even under a larger load, you can’t see any changes in the signal. I don’t know how it is handled with Hyundai/Kia, but at least with some German manufacturers I know it so that there are bullshit signals on the CAN bus, which show completely wrong values even without malfunctions. Therefore, my question, one of you has already taken a look at this signal by chance. ? My hope would be that it would show plausible values in other Stingern. That would clearly limit my problem.
