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.
