Most likely is your idle speed timing, there is either an adjusting screw, or you need the dealership to place a diagnostic tool on there threw the computer to set it down some.

I have a 94 Honda accord and when I turn it on it idle high. That when it's in park it idle high and low.what's wrong. With it and how can I fix it


check for vacuum leaks on hoses and connections as well as check intake gasket for leak by spraying carb cleaner around the gasket mating area,if rpm changes then that is where the leak is.

99 Eclipse 2.4 cid idles erratically and eventually stalls. Unplug the air flow meter and idle quality gets much better and does not stall. Does this mean I have a defective air flow meter? Engine codes...


couple of possible problems

first thing i would check is to make sure air intake hose between Mass air flow sensor and intake doesn't have any cracks holes make sure clamps are tight

secondly check for vacuum leaks carb cleaner works great for this spray around intake gaskets throttle body fuel injectors vacuum lines when spraying u notice change in idle (if idle picks up or stubles) that where your problem is example you spray around intake gasket and idle picks up you have bad intake gasket

third thing is to try and clean the mass air flow sensor they make special cleaner for this (u can use carb cleaner for this but it can leave residue on sensor and damage it so it not recomended)

my best guess for you with all three o codes is you have a vacuum leak somewhere

In my 2000 Saturn SL1 I am experiencing very high idle (2000 rpm warm - higher cold). I have cleaned the throttle body and the idle air control valve with no improvement. What next, replace the idle air...


You could try replacing the idle air control valve but I would obtain one from a local salvage yard, its cheaper and you are not certain if thats the problem, another thing i would check is your intake manifold gasket where it meets the cylinder head, if tha gasket is cracked or leaking it will allow excess air to enter the engine and make it idle higher, the easiest way to verify this is get a can of carb and choke cleaner and spray it all around the intake gasket area, if the engines idling characteristics change drastically then the gasket is bad and needs to be replaced if theres no change in the idle I would start looking for vacumm leaks and the idle control valve issue, which you specified.

Idel issue after air intake install


Your problem sounds like have air leakage from air induction system. I suggest you to re-check the gasket of Air Intake Manifold you installled or vacuum hoses for possible air leaking.
The easy way to check it, use Throttle Body or Carburator Spray Cleaner. Just spray around intake manifold where gaskets fitted and observe the idle speed, once the idle change or encrease, definetly there is air leak and you have check the gasket or replce it if necessary.
But if doesn't make change, I suggest you to check Idle Air Control Valve, check connector plug, lines and if you have donor unit try to do test part.
I hope you fix your problem and please update me whatever the result if you dont mind. Thanks

I have a idol problem with my car. please help


Idle problem like what? too low? too high? If it is too low it could be because your air filter is way too dirty or the throttle body has a bunch of carbon built up in it around the butterfly valve and gets no air at idle. If it is too high you have a vacuum leak. air sucking in from a cracked hose or intake manifold gasket. Check all your vacuum hoses and spray carb cleaner around the intake manifold gasket while the car is running.

Wide open throttle, replaced throttle body sensor and gear how do I check for vaccume leak


place your hand over the throttle plate if the engine stalls out u have no leaks. Take some Carb cleaner pray it around the intake system like around the gaskets or vacuum hoses if you hit the leak the idle will change.

My hyundai accent '95 misses when its cold.


Comment from the FixYa Moderator Staff:

I DISAGREE with the solution provided by Eliase.

You should NEVER spray 'starting fluid' in the engine compartment.

Starting fluid contains ether, and is extremely flammable.

Usage of staring fluid to look for vacuum leaks is a potentially dangerous situation.

I respectfully request that you refrain for using starting fluid.

What you CAN use, however, is a commonly found product, namely carburetor cleaner. This chemical is less flammable, and is used very often in the automotive business. Spray the carb cleaner near the intake manifold(s) where they connect to the block. If the idle changes, you have found the area that needs attention.

I would also doubt that you have a head gasket issue.

I replaced the head gasket and now it wont idle in gear ?


Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
