Hyundai Tucson acceleration lag or hesitation at low RPM despite air filter replacement on Hyundai Tucson

Some Hyundai Tucson owners report experiencing acceleration lag or hesitation at low RPM, even after replacing the air filter. These issues may stem from various factors, including transmission problems that result in slipping or delayed shifting. Additionally, faulty ignition coils can lead to rough idling and decreased fuel efficiency, necessitating inspection and potential replacement. Engine misfires, characterized by symptoms like loss of power and the activation of the check engine light, may also be caused by worn spark plugs or clogged fuel injectors. Furthermore, some owners have noted throttle response issues that could potentially be improved by selecting different drive modes. If these problems persist, it is recommended that owners seek a mechanic's expertise to diagnose and resolve the underlying causes, as driving with such issues can pose safety risks.
