These are the DTCs that are showing. The program is setup to look at an automatic transmission so ignore the transmission codes. the two codes that stand out to me are 16 and 48. That is the MAF and Distributor code. I did put an extra MAF on that I had last week just in case, all of the connections internally appeared to be good. I am assuming that the distributor code is telling me that something is wrong with the OPTI. I ran it long enough this morning long enough to go into closed loop. I did notice that the O2 sensors look a bit off. LT and ST look like it is trying to compensate for something that is going on with bank 1 which is the same bank that we originally diagnosed as not firing on the back 3 cylinders. I will add a screen shot of the most recent scan.
I noticed that it is hard to see. code 16 is "distributor ignition system (low resolution pulse)"
