90 ford thunderbird sc
I am pulling a code 24 and 66. I already replaced the ACT and checked the coil pack. The car runs so rich black powder is coming from the exhaust. The only thing left is the Mass air flow sensor or vane air temp sensor. I dont think or cars have a vane air temp. sensor. can anyone give me some help or lead me into the right direction thanks. its about 11 degrees outside if that has any affect.

Running very rich can definitely be attributed to a faulty mass air flow sensor. If you haven't tried cleaning it, I'd do that and then reset the computer. Then I'd try to find a replacement. I would check the air temp sensor to see if the connection to it is good or if the sensor is damaged.
