I have a 1995 850T5R Wagon that just came up with a Lambda light. Checked the codes and the only error I am getting is on the Fuel Management system plug is 121 which is, I believe, MAF.

What do y'all recommend here? Should I take the MAF off and clean it out or do I need to start scouring the local shops here in central Finland to find a new MAF? BTW there are no drivability issues and fuel is economy is where I expect it. Also light went off on dry day and now as it is wet and cold it came back.

TIA Alex

 

I would check for vaccum leaks and clean the MAF and see what happens from there.
