hmmmm. I have also mucked around with the knock sensors and a variable pot. No difference on my car - but once the pot fell off mid acceleration and the car lost heaps of power as it thought the knock sensor wasn't there anymore.

On my car open loop wouldn't come on until 2800 rpm from memory. I had one of those autospeed air/fuel LED thingos on each sensor and it stayed in open loop for ages and just wouldn't go. Once it hit closed loop it was obvious and away the car went.

Your car should leap from the line being a UZZ31 with headers. I can't think what would be at fault making your car do what it does. Very frustrating. Your car shouldn't change temp like that so soon though. It might not be related - but perhaps that should be sorted first of all.
Perhaps an investigation of the cooling system is in order first of all. I haven't heard of the temp sensor stuffing up. I have measured the resistance of the temp sensor with temp and it was the same as the one in the 21st century book - I don't have the figures any more.
Basic stuff like plugs, wires, filters - are they all ok?
