"code 17 Data exchange malfunction between individual control module.
code 13 02S control system operating to rich for lean limit (replaced 02 Sens and it did nothing also drove it for a week completely unplugged and that had no effect either)."
Man, that sounds like a possible harness issue. Sensors going wack and data fail between modules.
Pulling the O2 connector should have tripped a new code or changed engine behavior. Mine ate the MAF and the crank position sensor at once. The result was strange operating issues like you describe.
Might be worth it to have a shop scope it. They have some trick-tools that zeroed in on my 94.

So I went back to my ohm test of the the coils and remembered that the middle one had a reading of 3.45 when the others were pegged at 2.81 on the nose. I figured that the resistor in the coil was going bad so I went and bought 1 coil and threw it in there. So far it is better but the real test will be on cold engine (which in Chicago it won't be a problem get) I should know more later but this is promising.
