1995 Volvo 960

Engine Performance problem
1995 Volvo 960 6 cyl Two Wheel Drive Automatic 125000 miles

I just started to have trouble with my 1995 volvo 960 real rough idle pulled into a garage with a mechanic who seemed to know right away it was my Mass air flow sensor. We unpluged it and the car ran great. I have a new sensor coming today. I also pulled trouble codes by putting wire lead in position 2 of block A.I got codes of 121,223, and 322.

I got these codes with the air flow sensor unpluged but I think the error code stays there anyway from the original problem. And the check engine light is on.

can you tell me what each code means.

Thanks in advance

I don't know if I did it right but I asked the question below and made a donation. Do I just wait for a reply

Yep. Thanks for the doation, here are the definitions.
121=Mass Air flow signal
223= No idle valve signal
322= Airflow meter hot wire, that one of the heated wires in the MAF.
