Well hopefully you didn't do any damage to the computer but there is an adaptive relearn procedure that your vehicle will go through. Some vehicles are worse than others. I'm not sure how long you have been trying to run the vehicle but it does take a little time for your vehicle to learn its idle. You may also want to have any codes pulled from your vehicle that most auto parts stores will do for free. You may have done a little damage since you did blow that fuse cause evidently you shorted something when replacing the battery. One other thing is that you may want to clean the throttle plate on the vehicle. If there was a lot of carbon build up your throttle plate may be open a bit and it doesn't want to learn its idle because the throttle position sensor thinks its off.
Improving fuel economy is easy - just take it easy. It willmake your vehicle last longer, too. Here are some specific tips on how to savemoney on both fuel and repairs.
Keep your tires inflated at the correct pressure. Under-inflation causes tire wear and wastes fuel.
Do not carry unneeded weight in your vehicle. Excess weight puts a heavier load on the engine, causing greater fuel consumption.
Avoid lengthy warm-up idling. Once the engine is running smoothly, begin driving - but gently. Remember, however, that on cold winder days this may take a little longer.
Keep automatic transmission selector lever into "D" when engine breaking is not required. Driver with the selector lever in "4" will reduce the fuel economy. (This is referring to vehicles with Automatic drive)
Accelerate slowly and smoothly. Avoid jackrabbit starts. Get into the high gear as quickly as possible.
Avoid long engine idling. If your have a long wait and you are not in traffic, it is better to turn off the engine and start again later.
Avoid engine lugging or over-reversing. Use a gear position suitable for the road on which you are traveling.
Avoid continuous speeding up and slowing down. Stop-and-go driving wastes fuel.
Avoid unnecessary stopping and braking. Maintain a steady pace. Try to time the traffic signals so you only need to stop as little as possible or take advantage of through streets to avoid traffic lights. Keep a proper distance from other vehicle to avoid sudden breaking. This will also reduce wear on your breaks.
Avoid heaving traffic or traffic jams whenever possible.
Do not rest your foot on the clutch or break pedal. This causes premature wear, overheating and poor fuel economy.
Maintain a moderate speed on high ways. The faster you drive, the greater the fuel consumption. By reducing your speed, you will cut down on fuel consumption.
Keep the front wheels in proper alignment. Avoid hitting the curb and slow on rough roads. Improper alignment not only causes faster tire wear, but also puts an extra load on the engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle free from mud, etc. This not only lessens weight but also helps prevent corrosion.
Keep your vehicle tuned-up and in top shape. A dirty air cleaner, carburetor out of adjustment, improper valve clearance, dirty plugs, dirty oil and grease, breaks not adjusted, etc. all lower engine performance and contribute to poor fuel economy. For longer life of all parts and lower operating costs, keep all maintenance work on schedule, and if you often drive under severe conditions, see that your vehicle receives more frequent maintenance.
I suspect the Idle Air Control Valve. This is not a piece you can test without the proper computer diagnostic machine. A local shop may be able to hook up and diagnose it for you for a relatively small fee ( usually less than $50).Before you take it in though, I would try locating that control valve and spraying it down with Carb cleaner - It might just need a good bath!!! You didn't state the vehicle specifics, although there may be more than one place the manufacturer put them according to the year, so getting a repair manual would serve you well. I would not suspect the Mass Air Flow (MAF)sensor or the Throttle Control Module (TCM)since according to your statement it drives fine - it's just the sitting at idle that is plaguing you.I hope this helps - and thanks for using Fixya!!
If you mean when the vehicle is supposed to be standing stationary, a slight inclination ot move forwards on a level road is normal in an automatic. If the pull is excessive, the simplest thing is to reduce the idle speed slightly. If this does not answer your question, please give us a little more clarification on what you mean.
Hey there jonablac,
well if it starts and then takes a minute to start up all the way from trying to die or cut out the you need to turn up you engines idle speed or if it starts then dies and won't start again wait a couple of minutes and then try to start it back up beacuase it could mean your engine has gotten a little flooded or you don't have you vehicle's engine idiling speed adjusted fast enough.
A leak such as that meaning the fuel pump where as the fuel pump on your vehicle, is/should be battery operated, I would check to see IF timing is off a percentage, also take the fuel line off the carb. have someone turn the engine over you hold the line in a container to check it out...also we have found simple things like the floor mat under the accelerator was bunched up...??
There is a faulty sensor or valve. Sounds like a valve. The best thing to do, is take it somewhere that can diagnose the trouble code. Autozone can I believe, and they can tell you exactly what's going on with it.
