My 2004 IS300 has 120K miles on it. It is starting to abruptly lose a little power as it cruises along at highway speeds. It like I lifted off the pedal for a second, then is returns to normal power. What could be some causes of this. I recently had a DTC and I replaced both the throttle position sensor and accel pedal sensor. The pedal sensor was causing the DTC.
