First symptom sounds a lot like a sticking idle speed regulator.
Do you know which Fuel Injection system you have? Bosch LH 2.4, 2,4,2 or Lucas?
Since you mentioned LPT, I'm guessing you're not in the States, where we never got a C900 LPT (or the Lucas injection).
Second symptom could be related to the first. The only other thing that pops quickly to mind would be the throttle position potentiometer. But that's only in the LH 2.4.2. I am not sure if the Lucas system uses a potentiometer, or switches like the LH 2.4 does. Of course, that doesn't matter if you don't have the Lucas system.
Below is a link to a Bosch LH parts summary I created. You might find this helpful.
