As discuted in "Hold button on sohc automatics????", it seem that on my car (Canadian 95 Protegé S, 1.8sohc manual), the fuel is cut at 6750rpm. Isn't it supposed to be at 6000rpm? What could that mean. I went to a ride tonight to see exactly went it cut, and thats 6750rpm. So i'm wondering, could it be my tachymeter that is giving wrong data? i brought that instrument cluster in a junk yard, because it had rpm, and the stock one in my car doesnt. So it is maybe broken. But on idle, it seem ok, sitting at 750.
