I ran a cell check and it reported a faulty maf, so i replaced it and thought id have a looky at the plugs! there are realy light brown copper like colour!! would this be due to the failing maf??
Thanks

 

Should be a light sandy colour with some light deposits,

the coppery colour may be ok,

how do you know the maf in dodgy??? have you had your mixture checked,, the maf may be due to an older concern, that has been rectfied

Just a thought
