So what was the resolution??? I have same 4500rpm problem.

Cleared codes and it has no new ones but still does same thing.

 

um if the ses light is flashing it is the safty emergincy system ses aka airbags and safty restrants. some one preveusly removed the original stering wheel to replace the turn signal, or the sensor in the front or the back of the car is going bad. slim chance a air bad check that problem out fast replacing the airbag is expencive 3k for a dash bag for a 04 monty and 8k for an 07 and this is a dealer item. check out the ses light fast i mean fast dont want the air bags to deploy when driving.
