I am only trying to pass a smog test so I can renew registration (which this has already added up since I can't pay it till I get these problems fixed) so I had the map sensor and boost sensors replaced, changed oil, cleaned the throttle body and replaced the thermostat...which took care of all the codes it was throwing, then all of a sudden check engine light comes back on and i'm getting code p0107. Does anyone have any idea if this is maybe the idle sensor now? or something else? also, how many idle sensors are there it looks like possible 2? So frustrated so any suggestions would be greatly appreciated!!!

According to my Maxiscan MS300 code reader manual a po107 fault is 'MAP/BARO Circuit low input'.
Cant offer advise on that. sorry.

Problems That Trigger the P0107 Code

Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is defective
Faulty or corroded Manifold Absolute Pressure Sensor/Barometric Pressure wiring or connections

Did you check the connections and wiring to the MAP themselves?
A bad ground connection can apparently cause the check engine light to come on.
