Why is your NISSAN 200SX sometimes stalling at 100kph?

Your Nissan 200SX may be stalling at 100 kph due to several potential issues, including fuel delivery problems, such as a clogged fuel filter or failing fuel pump, which can restrict fuel flow to the engine. Additionally, electrical issues like a faulty ignition system or malfunctioning sensors (e.g., MAF or crankshaft position sensor) could be causing the engine to misfire or stall. Lastly, check for vacuum leaks or issues with the throttle body that might affect engine performance at higher speeds. It's advisable to have a professional diagnosis to pinpoint the exact cause.
