Replaced every thing in the EGF. System and the OBD still points to it as the
system problem. No vacuum leak in vac lines. Need help. Thinking new EEV
IV is next.
Are you referring to the EGR system? I have never heard of anything in a Ford called EGF, is the code you are trying to fix the one about the valve position or the one about feedback control? If you have one or both of these go and remove the sensor grounds and clean then throughly and then make sure they are reconnected and everything is tight. Then remove the hose from the EGR feedback control box and make sure it is flowing properly so feedback unit can detect the pulses in the exhaust system, then clear the codes and drive it and hopefully the codes stay gone, were there any other codes that came up?
NO EECIV in 1987. Whats the vehicle doing?which engine! 2.9 German?
