Jeep Wrangler engine will not turn over 1500 RPM under load but runs fine in neutral on Jeep Wrangler

Some Jeep Wrangler owners report experiencing issues with their engine struggling to exceed 1500 RPM under load, despite running fine in neutral. This problem may be linked to a lean condition, which can cause low RPM power and stumbling, particularly between 1900-2100 RPM. Additionally, some owners have noted intermittent surging or bucking under load, suggesting potential fuel delivery or sensor issues. A loss of power around 3000 RPM has also been reported, possibly related to recent transmission work or fuel filter problems. Furthermore, occasional stuttering or misfiring when coming off idle, especially below 1500 RPM, may indicate underlying fuel delivery, ignition, or engine timing issues. To diagnose the problem, owners are advised to check for error codes, assess fuel quality and air intake, and consult a mechanic for a thorough inspection to identify the root cause.
