ok my mfa has just startsd reading 99.9mpg,i read on the old forum you could remove and replace a fuse i just looked at the old forum f.a.q page but it doesnt say,can anyone help
sounds lke the vacume line has come off or got a hole in it momewhere between the manafold and the dash, any way I think its fuse 15 for mfa reset, take it out for 2o minutes, then replace, but I think its gonna be the vac hose though.
