I have an 86 bronco II with 2.9l. It is hesitating, surging, and shutting off randomly. I had this problem last year. At the time I ended up replacing the Distributor cap, rotor, and ignition control module. I pulled some codes that pointed to the egr system. Then replaced some vacuum lines running to and from EGR, the EGR solenoid, but it didn't seem to help until I replaced the EGR valve. Everything seemed ok, but now its starting again and worse. I've pulled the KOEO codes again and I get 34(o) and 67(o). Also 63(c) and 32(c), which is what was in memory.
My book says 34(o) is "EGR control circuit fault" or "Defective EGR pressure transducer sensor" I guess that is the EGR Sensor? or?
I don't understand what code 67(o) is. I tried unplugging the EGR sensor to see if it made a difference and it did not.
Just wanted to get an idea of what I should do to figure this thing out.
