Sounds like the TPS needs initial adjustment-won't hurt to check the AFM

Suggested Repair

Check and set the initial throttle position sensor (TPS) adjustment, and also inspect the air flow meter (AFM).

Conversation Summary

A 1997 Nissan 4x4 pickup with a newly replaced 2.4 engine starts and runs well but cuts out above about 2500 rpm, similar to a rev limiter. The expert suggested the TPS may need its initial adjustment and that the AFM should also be checked.
