The temp sensor bettween the intake manifolds only activates the cold start valve ie it only helps to start the engine when cold it should not affect the running. If its a fuel pressure problem it will run rough when cold as well as having a poor idle. If its the aux air valve it will just idle badly - once you are going there should be no difference Don't mess with the fuel pressure reg on the injection meter - you can check that there is enough enrichment when the engine is cold by checking that the Co is higher than when its at running temp. Then its down to the warm up regulator or possibly the lambda sensor ? On the LH system the wires are self cleaning when you switch of the engine you will hear a faint click from the control box after a few seconds - this is the wires being heated up to burn off any contaminants.
