Why does my ute run bad some days?
Can anyone tell me why it is that some days I can jump in my ute and it runs oh so smoothly and quietly and feels like its 200 kg lighter than what it is and the very next day its like a different car altogether, doesnt pull hard, engine sounds rattlier, like tappets, and runs noisy and rough. I originally thought that fitting the exhaust and Unichip might iron it out a bit but it has made no difference. Then i heard that the Unichip doesnt alter anything in closed loop mode, if thats true, whats the point because running around town wouldnt it mostly be in closed loop? Any info to help my understanding would be much appreciated.
