I don’t really know how to explain this, so bare with me. While driving and accelerating normally, my car suddenly slows down with no warning, this usually only last a few seconds then it kinda pops back to life and I’m accelerating again. This happens in both 2nd and 3rd gear. There’s no noise that I can hear when this happens, it just feels as though the car is about to stall, then it comes back. No engine light. Could this be an issue with the oxygen sensor?
