Some Nissan NV3500 owners report experiencing high engine revs, improper shifting, and sluggish acceleration, which may indicate several underlying issues. These symptoms could stem from transmission problems, such as low fluid levels or a malfunctioning transmission control module. Additionally, fuel system issues like clogged fuel injectors or a faulty fuel pump may contribute to poor acceleration and high revving. Ignition system malfunctions, including failing ignition coils, can also affect engine performance.
