It hardly ever wants to idle low or die, mostly an increase in rpm. And most of the time when I start it it runs up to 1000-1200 rpm for a second.

do you have a flash tuner?? My truck does the same exact thing you are refering to, you most likely do not have a concern w/ a sensor or the tech that diagnosed this concern would have reported a DTC, did they guess at the ICP and IPR?? so they know it has a HPO/ICP surge. I know what is wrong w/ it-please expain exactly what is does in detail so I can be certain. If you have a Boost guage does it fluctuate when you stomp on the throttle but not too bad down lower in the RPM range??

Barometric Pressure Sensor

THIS IS FOR A 6.0L ........
The Barometric Pressure (BARO) sensor is a variable capacitor sensor that processes a signal indicating atmospheric pressure. This allows the PCM to compensate for altitude. The PCM uses this information to calculate injection timing and glow plug control. The BARO sensor is located behind the lower steering column opening finish panel.
A BARO sensor fault will result in an out-of-range signal to the PCM

FOR A 7.3L here ya go:
Barometric Pressure Sensor
The Barometric Pressure (BARO) sensor is a variable capacitor sensor that processes a signal indicating atmospheric pressure. This allows the PCM to compensate for altitude. The PCM uses this information to calculate injection timing and glow plug control. The BARO sensor is not a stand-alone component. It is contained in the PCM.

A BARO sensor fault will result in an out-of-range signal to the PCM. The PCM will assume a default value of 100 kPa (14.5 psi)

18vtx00, when I start it it will rev to 1000-1200 rpm for a second then come back down to idle, it does not always do this, but when it does it will have a rolling idle then a jump in rpm with no particular pattern. Also when it is in this state it doesn't want to return to idle when stopping, it wants to stay at around 1000 rpm when it should be idling. No fluctuation in boost when I stomp it, it boosts to 26 lbs. No tuner
