Just a thought. I had the control knob strip on my o2 Century so that it would not turn the control shaft when you turned the knob. Dealer had a new knob in stock for a couple bucks. That took care of my problem Good Luck Rojeur

By the way, you can also get control knobs at auto parts stores. My 2000 Century had a knob break, took it to a local store and visually matched to one of theirs, works fine, looks 90% like the original.

I would encourage you to take your vehicle to your local GM dealership to be looked at. Please keep us posted when this has been taken care of.

it could be an exhaust leak, also the inlet and outlet tubes to the EGR could be clogged, also improper set of the EGR gasket.
in addition, you can check:
Check for the following conditions:
Important: Remove any debris from the connector surfaces before servicing a component. Inspect the connector gaskets when diagnosing or replacing a component. Ensure that the gaskets are installed correctly. The gaskets prevent contaminate intrusion.
Poor terminal connection. Inspect the harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and faulty terminal to wire connection. Use a corresponding mating terminal to test for proper tension. Refer to Diagrams.
Damaged harness. Inspect the wiring harness for damage. if the harness appears to be OK, observe the sensor display on the scan tool while moving connectors and wiring harnesses related to the sensor. A change in the sensor display may indicate the location of the fault.
Inspect the PCM and the engine grounds for clean and secure connections.

Its a rheostat for the fan switch that is located below the glove box near where the floor and the firewall meet...I found the exact location by using the autozone website parts location search tool...the rheostat was like $6.00 but it was a little difficcult to get at...small 7mm screws in a tight spot ...but do-able. The loss of the lower speeds on the fan switch is a typical indication of the rheostat failure.
