Massive drop in MPG
I have a 92 FD3S and for some weird reason after owning the car for less than 9 months, my mpg dropped from 17-18mpg all the way to 10-11mpg. I havent done anything but replace a couple of vacuum lines. Stock ECU, stockport, stock turbos and injectors. I know I am slightly behind on spark plugs and oil change. Vacuum is at 17-18(whatever vacuum is measured in). I dont drive it any differently than when I first got it but it is my daily so I notice just about every slight change. My exhaust too hot sensor broke so I have the warning light on the dash but I dont think it would cause me to run rich. I can basically smell raw fuel coming out of the tail pipe at idle. Compression is good above 110psi on a 73k motor. What do you guys think happened?
