I am experiencing issues with my 2021 Stinger GT1 3.3L AWD. Occasionally, when I accelerate at highway speeds, I get a weak throttle response and the car will stutter and kick forward erratically. The first time this happened, the car went into limp mode and I had to pull over and turn off the engine. Now, whenever it happens, I just coast without accelerating too much and wait a few minutes before I regain power. I cannot reproduce the issue; it tends to occur when the car accelerates at a higher gear for too long, rather than downshifting. I have HKS gapped plugs, use 93 octane fuel, have BMS air intakes and a muffler delete, and recently installed a pedal tuner (the issue predates this). I am using Map 1.
Any help would be greatly appreciated!!
