Get only cut out on me once on the way home. Keeping an eye on the gauges, clock excetera, everything else appeared to have power. Again running along perfectly smooth and motor just cuts out completely as if a switch was flipped. Pushed in the clutch, turned the the key off and back on and let out the clutch and it fires right back up as if nothing was wrong.

The ignition switch module in the column was replaced about a month ago before I started driving it. I suppose I could have a bad one. I guess this goes for the TFI too. Still have my old one that could go back in.

I dumped the codes and only got to the expected 81, 85, 82 with the engine off and 94 and 44 while running.

Swapped the TFI back to my old NAPA one and that has appeared to solve the problem. I have about 300 miles without any issues. I went ahead and put in the new O2's and that has seemed to smooth out the motor some at idle and on acceleration (if thats possible).
