2005 Regal 3.0 displacement throttle?

2005 Regal 3.0 displacement throttle. When there is too much carbon deposit in the engine, the gasoline sprayed by the fuel injection head will be absorbed by a large amount of carbon deposit during cold start, which leads to the lean mixture during cold start and the difficulty in starting. The gasoline adsorbed by carbon deposit is not saturated and is not easy to run. Carbon deposition in the fuel nozzle will cause different fuel injection quantity in each cylinder, which will lead to engine jitter, or when there is too much carbon deposition, the spark plug will not work and the engine will shake.

Description of displacement throttle valve

Too much carbon deposition in the throttle will also lead to difficulties in starting, idling jitter, accelerated flameout and other failures. At the same time, it is necessary to check whether the throttle position sensor works normally. At the same time, when the engine is running at low speed, because the engine pressure does not keep up in time, it will not get a good mechanical running state, which will cause the engine to shake.
