Coaster idling high and high fuel consumption


Water temperature is low cost oil is certainly the easiest way is with a hard shell to block part of the warming effect of the radiator well as for how much you want to try to stop. Idle temperatures will rise up relatively low. What is the pull speed? Not run fast but continues to run uninterrupted some time. Usually two hours can be. Is to allow the engine to reach full swell purpose. Such a shift is to be based on the vehicle speed and the reference engine speed. Not based on the engine speed. Driving is probably the single 30 towards third gear, fourth gear towards forty, fifty five-speed ahead. Many people on the car ahead of change. As long as the engine sounds smooth, no trailer can be.

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.

I turn on ignition and vehicle starts to idle real high seems like accelarator cable is sticking


Hi Clucas, If you're talking about a cold engine, the vehicle is fitted with an automatic 'up idle' system. Depending on how cold the ambient temperature is. The colder it is outside the higher the idle, until the engine reaches normal operating temp. The engine should then settle down to the correct idle speed. If however the cold start raises the speed to more than 1350, have a scan carried out. If the idle speed is always at a high rpm, do the same.A leakage of air into the intake manifold can also cause the latter problem. A leakage however will not be evident via a scan.

I have a 1990 Ford Ranger 2.3 very high miles. Vehicle runs, starts and idles well. Does not visibly burn oil. Check engine light comes on at around 65 miles an hour after vehicle is warm. If you slow down...


Best guess with the information provided is restricted flow of the catalytic convertors.At higher speed the rpm's stay consistant. If the cats are not allowing the exhuast to push thru unrestricted the engine will know its labored but not why.

How to use cruise control


Here are the steps in using cruise control:

  1. Get on a road you will be traveling at the same speed for a long period of time, such as a freeway.
  2. Reach your desired speed. Choose a speed that allows you to move with the flow of traffic and not go over or under the designated speed limit for that road.
  3. Locate the ON and SET buttons on your steering wheel. Press ON first and SET after. Your cruise control is now activated. Most vehicles must be traveling at least 30 miles per hour to set the cruise control.
  4. Press and hold the SET button if you wish to use cruise control at a higher speed. Hold until your desired speed is reached.
  5. Decrease speed by pressing the COAST button.
  6. Push the brake pedal to disengage the cruise control function. If you wish to return to the previous set speed, use the RES (resume) button. You must be traveling at least 30 miles per hour for this function to resume.
  7. Erase any previous speed by pressing the OFF button.

My prelude wiil not accelerate past 30 to 40 miles per hour, starts fine, idles fine run fine beloww about 30 or 40 mikles per hour, does not really miss but will not accelerat past 30 or 40


Generally the symptoms say the catalytic converter is clogged, you can't get any air out so you can't pull any air in, and the age of the vehicle says so too. Look and see if it has ever been replaced.
