What does this mean? 700

posted by  someone claiming to be lewismug on  Thu May 6 08:23 CST 2004 [RELATED]

I cleared all the codes in my car, ran it to town and back and then re-checked them. I am now only getting a 3-1-2.

3-1-2
Signal missing for knock-related fuel enrichment
Wiring break between EZK terminal 4 and FI #28
No faults evident

What does this mean? My car is running the same as before, kind of rough and still burning more gas than before the head swap. I unplugged the vaccum line from the Fuel pressure regulator and it ran a little better, and I did smell fuel in the vaccum line. If I unplug the AMM, it runs a little worse, but I can still drive the car down the interstate at 80 mph. It still acts like it is flooding out and I get a lot of hesitation while driving the car. I can drive the car 30 miles and it burns a quarter of a tank of fuel! What gives! Where are all of the Volvo GODS when you need them!
