Car should run fairly clean without the PMS if everything else is correct. As stated earlier, the factory ECM on a Fox Mustang is fairly adaptable on it's own. The PMS just allows for fine tuning and raising the rpm limit.

ECT - I assume that would require a sensor which is no longer on the engine lol. I'm betting it screwed into a port in the lower intake on the driver side...you saying I must have it for the engine to run properly? Is this the sensor here? Can it be installed in the intake instead of that tubing?
Not having both factory O2 sensors hooked up is causing problems I am experiencing? I guess my basic question now is what is the minimum amount of changes I can get away with right now. The PMS can control everything over 2000rpm...all I need is to get it to run/idle cleanly atm.
