ford taurus,rich fuel mixture Posted 7-2-2003 03:09

hi,everyone.i have a 1993 ford taurus wagon with a 3.0liter.i have been having a problem with a rich fuel mixture.i took it to a repair shop and had the computer scanner put on it ,and it gave three codes.the first was 335-egr signal out of range,the second was137-no ego-rich fuel mixture and the last was326-egr signal to low.so i replaced the egr sioniod, the fuel pressure regulater,the temp sensorand all the basics,the plugs wires dis cap and rotor,and air filter.also i found a leak in the egr exaustreturn tube,so i also replaced it.i did a vacume test on the egr ,and it is working fine.i also checked to make sure that the air intake manifoldand egr was not plugged and still i get a rich fuel mixture.as you could amagine i am now lost as what to do next.so any input would b greatly apreicated.thank you.
