When air conditioners or alternators or such come on, the computer will raise rpms to cover the load.

Tip

Save Money on Gas/Petrol


  1. Avoid idling. While idling, your car gets exactly 0 miles per gallon while starting the car uses the same amount as idling for 6 seconds. Park your car and go into the restaurant rather than idling in the drive-through. Idling with the air conditioning on also uses extra fuel. Also, avoid going so fast that you have to brake for someone. Whenever you brake, you waste the gas it took to get going that fast.
  2. Drive at a consistent speed. Avoid quick acceleration and hard braking. Cruise control will keep you at a constant speed, even when going up and down hills.
  3. Avoid stops. If approaching a red light, see if you can slow down enough to avoid having to actually stop (because you reach the light after it is green). Speeding up from 5 or 10 miles per hour will be easier on the gas than starting from full stop.
  4. Anticipate the stop signs and lights. Look far ahead; get to know your usual routes. You can let up on the gas earlier. Coasting to a stop will save the gasoline you would otherwise use maintaining your speed longer. If it just gets you to the end of a line of cars at a red light or a stop sign a few seconds later, it won't add any time to your trip. Ditto for coasting to lose speed before a highway off-ramp: if it means you catch up with that truck halfway around the curve instead of at the beginning, you haven't lost any time. In many cities, if you know the streets well, you can time the lights and maintain the appropriate speed to hit all green lights. Usually this is about 35 to 40 MPH.
  5. Slow down. Air resistance goes up as the square of velocity. The power consumed to overcome that air resistance goes up as the cube of the velocity. Rolling resistance is the dominant force below about 40 mph. Above that, every mph costs you mileage. Go as slow as traffic and your schedule will allow. Drive under 60-65 since air grows exponentially denser, in the aerodynamic sense, the faster we drive. To be precise, the most efficient speed is your car's minimum speed in it's highest gear, since this provides the best "speed per RPM" ratio. This is usually about 45 to 55 miles per hour.
  6. Use A/C only on the highway. At lower speeds, open the windows. This increased the drag and reduces fuel efficiency, but not as much as the AC at low speeds (35-40 mph). The air con - when used a lot - is known to use up about 8% of the fuel you put into your car.

Car won't pull back speed when foot off accelerator


Very possibly a vacuum issue. Maybe a line that needs vacuum for the trans is on an inlet that effects the throttle. Not sure how old your vehicle is.

I have a 1999 dodge dakota, manual 5 speed, 5.2L V8, The problem I am having is the idle when standing still is about 1100-1200rpms. When driving and I depress the clutch or put in nuetral the rpm's...


The most common cause of high idle is an intake air leak. It will cause a lean condition to the O2 sensors and the PCM's solution is to increase the fuel mix resulting in faster idle. It can also cause a Check Engine Light if the idle remains too high for too long. Do a smoke test or soapy water test around the intake manifold and throttle body. If you detect any leaks, seal them and try again.

Idles low when ac/heat is on and lights dim


fix the idle speed to 850-900 rpm
check the alternator and voltage regulator as the voltage should read 14.5-14.8 volts dc at 1000rpm or higher regardless of what is running
have it bench tested by an accredited auto electrician

Hesitation or stumble during acceleration


take your car for a tune up
if they are carburetor type motors you may need your carbie cleaned and a tune up
if you clean it your self with carbie cleaner it may increase in idle speed this is nothing to worries about it is a simple adjustment
with a carburetor type motor they tend to idle higher when their cold this is the automatic choke kicking in and normally it should happen till the car is a bit warmer and the accelerator has been depresses
although a car should idle at 800 rpm my paddok car dose when it is cold it idles at 1200rpm i like it this way as the car warms up quicker as i will not drive a car while it is cold
hope this helps
