Mass air running rich Reply #30 – May 02, 2013, 12:13:26 PM Quote from: 88turbo;414354car is back up and running again, I checked KOER codes and it gave me 44 and 94. the car seems to be running better at this point although I havent had a chance to actually drive it yet. 44 and 94 are Thermactor codes. I'm guessing it's gone? They won't cause a rich problem.You switched to the T-bird/Cougar 5.0 fuel system and the problem was solved? If so you may have had a fuel pressure regulator issue. At least it's running good now :). Quote Selected

Mass air running rich Reply #32 – May 02, 2013, 01:05:48 PM Speed density uses MAP which gets vacuum, when you mass air convert and rearrange the EEC connector, the MAP becomes BARO, and is no longer connected to vacuum, but left open to the atmosphere (barometric pressure sensor), same sensor put to a different use. Just thought I'd clarify on that. Quote Selected
