New to this site and trying to repair a 2000 S40...so what does this phrase refer to? I had the check engine light on and had the code read at an auto parts store and looked up P1241 and viola I get the above mentioned phrase--Manufacturer Controlled Fuel And Air Metering I definitely need some help here folks??!! ( I did search the site for this phraseology by nothing came back except that air is too generic a term...
