I'm guessing this is the right page for your error codes
E30: TPS was 14 degrees or more while ISC was retracting for 15 seconds,
or TPS was 2 degrees while ISC was extending for 15 seconds.
E39: Engine RPM was outside of the range expected for indicated vehicle
speed indicating a VCC engagement problem.
E90: Vehicle speed cycles from 30 MPH to 0 at least 10 consecutive times
with no VCC brake switch input.
E98: At a vehicle speed under 6 MPH, the gear selector was moved from
park or neutral into drive or reverse when engine speed was 600 RPM
greater than determined by PCM.
98 almost sounds like a code placed in there for waranty purposes.
39 and 90 make me wonder about a faulty wire harness to the tranny.
Adding in 30, may mean the wiring harness to the PCM is problematic.
This is just my thoughts with no expertise in the field.
