I HAVE A 81 BUICK REGAL AND THE CHECK ENGINE LIGHT IS TELLING ME TO REPLACE THE MIXTURE SOLENOID.
THE REPAIR GUIDE DOESNT TELL ME MUCH.
I PURCHASED THE PART HOPING IT WOULD HELP ME FIGURE IT OUT.
NO LUCK, NOT EVEN THE INSERT THAT CAME WITH THE PART.
I WAS HOPING FOR A STEP BY STEP ON REMOVING THE OLD PART AND INSERTING THE NEW.
ANY HELP WILL BE APPRECIATED.
THANKS IN ADVANCE.

The check engine light does not tell you to change any parts. It merely records data that it sees. The technician then has to determine what caused it. What was the exact code number recorded?

I HAVE ALREADY REPLACED THE O2 SENSOR.
IT HELPED A LITTLE BUT THE LIGHT IS STILL ON.

You have a number of different codes there that may or may not be related. Code 23 is telling you there is a problem with the control solenoid circuit. That may or may not be caused by the solenoid itself. It could just as easily be in the wiring or the ECM. Changing the solenoid requires disassembly of the carburetor and that is not something a novice should attempt. It's basically rebuilding the carb and that is no simple task. All the additional codes could indicate an ECM problem or various other possibilities. You may want to let a professional dig into this.
