This is in continuation to my question Fast Idle and High Fuel Consumption. I just bought a Manual 97 Mazda Lantis 323 1.8L DOHC 16 Valve BP ( apparently called a Protege in the US ) which has a fast idle and is consuming lot's of fuel, giving black smoke out the back if you rev the engine.

The previous owner told me that he recently replaced the throttle body and attached TPS with a second hand one from the same model automatic version:

Throttle Body Front View

I want to know if this makes a difference - it seems to me from the answer to my previous question that the TPS on the automatic and the manual operate differently.

The vehicles engine map will be the differance. If you are using a throttle body spec for a differant set up then it is bound to be wrong. The TPS may also vary on model to model.
