Honda Civic 98 OBD P1399 P0335 P0301 P0300 - Stalls at 3000 RPM, Poor Idle, Fuel Pump Failure Suspected
I own a 1998 Honda Civic 1.8L automatic model that suddenly starts jumping at 3000 RPM and fails to accelerate beyond that point. The engine barely idles, which raises concerns about possible fuel pump failure. The vehicle is showing OBD codes P1399, P0335, P0301, and P
Has a tune-up been performed recently? A lack of maintenance could be contributing to the engine misfires and performance issues.
