Hi and welcome to the forum! Congrats on the car, I'm sure you'll get it to run well.
I think you have a faulty temperature sensor or broken wire to the computer. It sounds like it's over/under fuelling. It could be an inlet manifold leak, but that should be easy to check.
You say your temp sensor is faulty - this is a seperate sensor in the thermostat housing. There are two: One has a bosch connector (that's the one for the engine management computer), the other has a tab connector. Try cleaning the connection first, but if that doesn't work, replace the sensor.
As for the temperatuer sensors for the computer, there is the one I just mentioned in the thermostat housing. I think that's probably the one that's faulty, but there's another one for measuring inlet air temperature. It's fitted in the inlet hose, after the air filter, before the throttle body.
To check the sensors, disconnect them and measure the resistance with an Ohm-meter: At 20 deg C, the air temp sensor should be between 283 and 297 Ohm. The water temp sensor should be between 283 and 297 Ohm at 20 deg C, and 383 and 397 at 80 deg C.
Good luck! Anders
