just wondering how do i test the maf sensor as my car seems to be overfueling ive done an ecu reset and checked it about a week later and everthing is fine cheers will

 

MAF issues usually lead to underfuelling however I wouldn't rule it out. Faulty Lambda sensor is the more likely cause of over rich running, this will however only be an issue on cruise as the lambda signal is ignored on boost.

When you say it's overfuelling how does it manifest itself and what model / year is your scoob?

 

its a 94 wrx sti saloon with k+n cone,apexi dump valve, 3"downpipe decat into 2.5" zorst apart from them its standard im getting about 15miles to the gallon town driving 4000rpm ish with a quick blip over that now and then

 

any1???

 

go to a mechanic who will put it on his diagnostic machine. mafs dont like cone filters.vibration is also bad
