I think the temperature sensor or wires are not working properly, my car doesn't seem to pull right, mechanically the engine is new with non-cat camshafts (which are more agressive) and lighnted crankshaft and ported heads it should make a lot more power but the car feels weak, its even hard to move it from stand still, I have to use a lot of throttle. Could it also be because Ive used denso ik20 (i think) spark plugs? Could the spark plugs make such a difference? What else could lead to default mode of ecu and how can I know if it is default mode?
