I changed out the air mass meter on my '91 940 Turbo, and now, after the car warms up, it misfires terribly and chugs down the road. Is there something more to do in the swap-out? I put the old one back in (it had no problem before, other than giving a trouble code - ran well), but it still runs rough. What should I do or check? Thanks!
