Is it better to idle in park or drive?
Keeping an automatic transmission in Drive puts an extra load on it, which drains fuel. In neutral, it’s resting — or at least as close to rest as an automatic ever gets.

As you spend more time idling, the average temperature of the spark plug drops. This makes the plug get dirty more quickly, which increases fuel con- sumption by 4 to 5 %. Excessive idling also lets water con- dense in the vehicle’s exhaust, leading to cor- rosion and a reduction of the life of your exhaust system.
What happens if you leave your car running overnight?
Ray: Well, to answer your first question, leaving the car running all day won’t do any damage. As long as the engine’s cooling system is working normally, a modern car can run for days and days — until it runs out of gas — without causing itself any harm.

Is it safe to sleep in the car with the engine running? NO, don’t do it.

This is a big risk because carbon monoxide is odorless and can cause death if too much is inhaled.

Why does my car vibrate when idle?
If the vehicle shakes or the engine shudders a lot when stopped at a stoplight, or when parked with the engine idling, it might indicate the motor mounts or transmission mounts are damaged or broken. … If the shaking decreases, it’s a strong indicator the engine’s motor mounts need to be inspected by a mechanic.
What causes lopey idle?
Lope is cause by the intake charge being pushed back up the intake tract as a result of late intake valve closing. This charge backs up through the venturi and upsets the signal that the carb is using to meter fuel with the incoming air.
Is sitting with engine idle illegal?
The Highway Code states: ‘You MUST NOT leave a parked vehicle unattended with the engine running or leave a vehicle engine running unnecessarily while that vehicle is stationary on a public road’. … However it is permissible to leave the engine running if the vehicle is stationary in traffic or for diagnosing faults.
