408 intake manifold replacement shall the throttle be changed together?

Change. According to the query of Pacific Auto Network, aluminum alloy throttle can be replaced at the same time, and the corresponding software version needs to be written. The intake manifold is obviously different. Oil and gas are directly absorbed and burned near the valve and will not accumulate at the throttle. The effective solution is to replace the improved intake manifold, so that the oil vapor can not accumulate into oil at the throttle, which can avoid reporting the fault.
