Idle speed is high on my geo metro what component in engine could be causing this?


vacuum leaks use wd 40 spray the connections if its leaking the speed will change if not it aint leaking ,other thing is has your timing has floated up! if? so reset distributor back is slower idle okay ? the last thing behind these 2 would be the throttle position sensor it is adjustable on some cars i have seen people loosen them run the motor then turn them back and fourth to set them to idle better (seems unlikely) the last and most serious may be your problem the rings and much the piston in these motors wear poorly" and when this happens excessive blow by enters the engine through the pcv valve try disconnecting the pvc when running is there a lot of blow by hold your finger over the pcv valve hose end is motor running much slower ! then you have blow by you need a good piston and ring replacement (beck arnold pistons 3 rings ) and hastings rings or if the beck arnold rings are available between all the above you are sure to find te problem

Feels like miss firing at higher speeds


Your caption says misfires at high, then you say low? You have a 95. Lots of miles I assume. So there are several things that would cause misfires at high and low. First is timing chain/belt, sloppy. Second, would be the valves and rings. Valves worn or bent, not seating right. rings just worn out, not holding compression. Do a compression test and see. Low speed or idle misfires can be from vacuum leaks. check hoses. Low and high rpm misfires can be from ignition problems. Wiring, coil/s, ignition modules.

How often should the ignition coils be changed on a 2005 honda civic lx special edition? Thank you!


In ordinary use conditions, the ignition coils for your Honda should last a very long time--possibly the life of the car. It's not uncommon to see Hondas with their original coils at 125,000 or 150,000 miles--or more. New coils do put out a hotter spark than older coils, but in ordinary use, even an old coil should still be firing well within Honda specifications.

If your coils are getting fried early (meaning, a lot earlier than what I just wrote), you might want to check the voltage going to them. Too high voltage will burn them out prematurely. That, in turn, could be caused by a malfunctioning voltage regulator, and that same overly high voltage could also be burning out your bulbs and headlights prematurely, as well as possibly damaging your sound system and on-board computer.

When running, your car's electrical system should not be exceeding 14.5 volts. More than a few cars are designed to max out around 14 volts. Make sure that you check output voltage at several engine speeds, such as at idle, at 2000 rpm, at 4000 rpm. You might notice some variation depending on engine speed, but a good voltage regulator will do its best to keep output voltage consistently over 13 volts. Some Honda alternators and voltage regulators are designed to cut back on output voltage at low RPMs, i.e., when idling or just bopping around town. That would tend to give you a seemingly low reading, like a battery's own 12.6 volts; it would not give you a reading that's too high.

What happens if the idle control valve on a 2000 honda accord is not immediately replaced?


The idle control valve (IAC) controls the idle speed by changing the amount of air that will bypass into the intake manifold. It's activated by the ECU (engine control unit; your computer) depending upon the running condition of the engine (A/C on or off, Power steering, cold and warm running, etc.). So, you may have some inconsistency in your idle speed, and you may burn a bit more gas if the idle goes a little high, or you might stall now and then, but I wouldn't think it was immediate problem situation. Don't, however, let it go on forever.
Hope this helps you.

1988 5 speed Honda Accord


Ensure your spark plugs,wires (ignition coil and spark) and your filters (air and fuel) are within 2 years of installation It's erratic at 800 rpm as the engine is cold and they like the 2200 range for 3 minutes before they kick down on their own. Press the pedal twice before inserting your key. The owners manual states depending on the outside temperature, the engine will require more priming. Update if possible.
