Recently bought my 2001 2.0Ex Accord (loving it) and since I've had it I've noticed a quirk which hasn't caused me grief up to now, but don't want it to bite me in the butt later! When I'm driving at night and park up, if I turn the engine off and take the key out before I turn the headlights off, the engine keeps running. If I turn the lights off the engine stops. Obv during the day this isn't an issue. Thoughts anybody?
