Yeah Sleeperz now that you put it that way, no wonder indeed I am wondering if maybe I have been running lean with both the zetec MAF and duratec MAF and now its faster because it is in limp mode and its finally rich enough. Any way I read the plugs tonight and they look good not too rich or lean. I need another MAF too and have been wondering if there is any other way to calbrate them for the correct amount of air without a chip?
