So I had weird things happening with my Civic. Was at the roundabout and when pulling off had around 2 sec gap when engine actually responded to accelerator being 80% pressed. When I went to 3rd gear same thing happened but for shorter time. Within this period car felt under power. Higher gears was all OK with nothing funny. No faults, nothing. It's a Honda Civic 1.8 Manual 2006 with 102k on clock. My first though was either sticking throttle flap or accelerator pedal sensor. Any thoughts? Maybe someone faced something similar?
