Car idles fine, but hesitates when accelerating from a stop. Once engine rpm’s reach 3000 car performs normally. Problem not as severe when engine is cold. I removed and replaced the engine temp sensor (no change). History: Check engine light illuminated. ECU code was fuel pressure low. I removed and replaced the fuel pump, fuel filter, and pressure regulator. No check engine light since maintenance performed.

Hi Bronco419,

I don't believe there is an error code for fuel pressure low. Can you please provide the code?

I would check the Throttle Position Sensor, O2 sensor, Intake Air Temperature and MAP sensor.
