Agree with Grant. Check the AIC motor. Again, if you can borrow a tester there is a "Reset AIS motor" test that you can fire. It will cause the AIS motor to close (RPMs drop to about 450) then go back to normal. If you don't get the drop, you have a failed AIS.
On the other hand, if you don't tear the gasket, it's easy to swap AIS from side to side.
Best regards,
Frank
