rpm 6500, in neutral is not good on any engine, parked hot or cold. use a real RPM gauge never trust any 20 year old suzuki cluster, best is read the scan tool , believe that.
driving down hill possible.
the OBD if in limphome mode , does on some sidekicks drop RPM limits.
(limphome means , spark advances is now disabled, 1 sensor is dead usually and not mimicked(crudely) closed loop dead, and rpm limits defeated, on some.
there is also , BLACK death mode called BACKUP by suzuki. (BLACK as in black fuel cloud every inch you drive)
BACKUP is when the CEL is dead, the DTC errors are all Dead, and ECU is dead for scans, that is right there is really 2 processors inside, 2 brains, not counting LIMP)_
1 is the full blown ECU processor, scan tool works.
2nd is a backup that is like a crudely simulated carburetor. (runs off throttle angle if TPS not dead or runs off vacuum and RPM only) ( I could make a ECu from scratch doing this way)
BACKUP mode the scan tool fails to communicate or the pre 96 cars, the CEL is DEAD as a door nail, and will never flash codes again.
Im sure yours is not in backup
but may be in Limphome. if any 1 sensor is dead.
