OBD reader shows code for coolant temperature sensor. When connected if it will start it runs badly. Disconnected it runs pretty good after it warms up for the most part. This code comes directly after replacing exhaust manifold, catalytic converter, and both oxygen sensors.

What is the exact fault code number? Typically it will refer to a sensor voltage too high or too low, and those are almost always due to a wiring or connector terminal problem.
