Why is my cars rpm so high in park?
Why is my cars rpm so high in park?
If the computerized engine control system is faulty, high idling can be one symptom. A vacuum leak in any of the hoses can be the culprit—inspect them all for leaks. A bad idle-speed control unit can cause the problem; it may need to be replaced. A faulty alternator can fast idle issues; if so, replace it.
Does putting car in park Save Gas?
The amount of fuel used is minimal, to keep the engine at idle rpm, but it does result in significantly lower fuel-economy figures while in neutral. However, there is a time when putting a car in neutral and coasting will return greater fuel efficiency—although it requires the driver to plan ahead.
What happens when I shift from Park to drive?
Every time I shift my truck from park or reverse into drive the engine rpms severely drop and sometimes stalls. It idles in park at ~750-800rpms and drops to ~400rpms in drive before it bounces back to ~700rpm. However if I start my car in neutral and shift into drive everything is fine.
What should the idle speed be in neutral?
In Park or Neutral it idles up at 1500. But when I drop it into drive it goes all the way down to around 600. This seems like an excessive drop to me. I had to set the curb idle high so that when it went into gear it wouldn’t stall out.
Why does my truck stall when shifting into Park?
