Is it better to idle in park or neutral?
Is it better to idle in park or neutral?
Even when parked while waiting at signals an engine will continue to consume fuel while idling. In general, for an automatic transmission, at a stop while idling produces a load on the engine and worsens fuel efficiency. Neutral Idle Control alleviates this fuel consumption and helps improve mileage.
What should the idle RPM be while idling?
You can get a cheap gauge at an auto part place that will quickly tell you if you are in spec. Idle air control..it should idle at 1000 rpm’s when the engine rpm’s jump up and down,suspect the iac.

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 the RPM drop when I put the car in neutral?
Check the timing both in and out of gear. If the timing is falling way back in gear, that’s most of your problem. Usual culprit is a centrifugal and/or vacuum advance kicking in at idle. As soon as you throw it in gear it drops back, making the RPM drop worse than it would ordinarily be.
When does the RPM go back to normal?
The RPM will usually go back to normal as you accelerate the vehicle, but will increase again after you stop. This is definitely not a normal situation. If you are experiencing a rough idle or your RPM is running high, then there are a variety of reasons for why this could be happening.

What does it mean when your car RPMs go up?
One of the things that goes unnoticed is a fluctuation in RPM’s whether at idle, or when driving. While many won’t see them, it should certainly be checked on every once in a while. Below are a few explanations as to what might be the issue and cause for that fluctuation.
