I had read in an article while researching mis-firing, the issue could be the coil, wires or plugs. I got to thinking that I was messing around the plug wires disconnecting and reconnecting my O2's so I went around and pushed all my plug wires in. I ran the car again and the mis-firing went away, but I do have a hesitation, slight, but if you listen, you can hear it. The idle is staying at 750 and the car does act up sometimes, but I blame age more than anything.Today (actually yesterday) I ran codes on the car. I noticed that the idle was low after finishing the exhaust and it seems to be missing every once in a while at idle. the codes came back that the idle was correct (and has not been an issue after running the tester) and that I still have 137/173 codes and I bet its the injectors are just crap and dumping fuel into into the intake, or at least one or two are crap.
