codes out of my 2003 f350

[pick]

here are the codes that came out of my truck this morning, 1- manifold absolute pressure- mass or volume airflow correlation. 2-tubro 1 boost control A preformance. 3- injector circuit 12345678 all of them. 4-cyl. 5 contribution or balance malfunction. 5- egr circuit malfunction. 6- egr recirclation senser circuit low sensor A. can anybody make sense out of this? i changed the injector harness yesterday it runs a little beter but it still misses and hesitates on the highway.

While the actual codes may have helped, I'll give it a shot.
1. The PCM uses a compareative value from the Map and Mass sensors to determine its fuel strategy. One of them is way out range or is unplugged. Check the plugins, I figure a plugged air filter or a massive air leak,
Air filter not seated correctly, filter sentenal not plugged into the houseing, something of that nature.

2. The A circuit of most sensors is the power circuit check the wireing to the turbo circuit.

3.Check the harness plugin at the FICM is fully seated on the first plug, and snapped in.. This is the PCM to FICM circuits. The injector harnesses are the next 2 plugs. One for each bank. Check them as well.

4.Check plug in for #5 injector. Since ya were moveing the harnesses aroung it may have pulled loose.

5. Five and 6 are related check EGR circuit wireing for short/open chafes etc.

Just a few things to check
