You have a leaking engine cylinder head gasket, that is the cause of the smoke and long warm up.

SOURCE: i have a 92 honda accord ex that the it idles go

If it does that when the engine is warmed up (full operating temp.) it may be you iac valve, or your fast idle valve. They get gummed up. It also could be your PVC valve, but probably not.:

IAC in red. Fast Idle in yellow. Your PVC valve is plugged into the valve cover (the black hose in between the red and yellow in the picture) it simply pulls out. It should rattle when shaken.
Hope this gives you a start on the problem.

SOURCE: my 92 accord idles up and down from 1000rpm to

I believe there are two fast idle cam valves in this vehicle.Only been several years since I've repaired one. One for the winter and the other for the summer. Your gonna need the shop manual to determine which one is which and where they are located. Now you said its fine "cold" so its the summer one. Short a shop manual what I would do is they are probably on the fire wall as close to the throttle body as possible. There should be two small philips on top of each one holding down a small plate. One at a time remove the screws and plate clean them out with a rag dipped in carb cleaner then squirt a drop of oil in one of them and close it up. Start the vehicle let it run and see what happens. If the symptom goes away you found your culprit now replace it. If it didn't work do the same on the remaning valve and see what happens. Again if the symptom relinquishes its the one you have to replace.The fix for these valves is replacement the squirting of the oil trick doesn't last that long. Good luck

SOURCE: My 92 accord idles when you first turn it on,but

check for a leaking or sticking EGR valve. This valve only operates when the engine is warm. Check also for vacuum leaks on other devices that are switched on when the engine is warm. A good example would be the evaporative emission canister or "charcoal canister".

92-94 honda accord idle problem


Do you have an early 90s honda accord that has an unusually high idle? Then as the engine warms up the idle might fluctuate up and down?
This is caused by the coolant passage to the idle control system that is clogged up. Try flushing it out first with water pressure such as a garden hose, and if that don't work you may have to remove the hoses and pipes and the idle control system to clean out all the coolant passage.

I have a 91 tercel that will not pass smog, unable to read codes, idles too high that if you put the car in gear before it warms up its jerks hard, appears to idle normally after warmed up, smokes pretty...


The smoking is probably due to worn valve guides.. the oil from the top..the head.. is leaking past the valve stem into the cylinder.. next morning or a few hours later when you start the car.. it burns this oil up..and the problem although still there is much less noticeable.. cause the amount leaking is minute..it's being burned as you drive.. otherwise it takes a while for it to accumulate.. It could mean a minor head/top end rebuild to a minor overhaul..

The emissions problem and the idle problem may be linked.

First make sure your throttle cable is clean and working properly. They can get dirty.. sticky..or even a weak spring.. but dirt rust and grime..biggest culprits.

There is an IAC (Idle air control) valve attached to the throttle body.. you may be able to spray carb cleaner into the closed throttle body to clean it.. You may need to replace this part. It can really get clogged with carbon.. and cause this high idle problem.

Next.. replace or remove/clean/reinstall the EGR valve...probably better off just replacing it.

Check all vacuum lines for cracks..replace as needed..vacuum hose is cheap.. and lastly.. do a minor tune up.. plug wires.. plugs (properly gapped of course). air filter and fuel filter..

Your car will probably pass the smog check even with the cold startup burning oil issue.. that's not what's causing it to fail..it's the EGR valve and possilbe lack of recent tune up.

You can continue to add oil between changes.. use a heavier weight.. and check often.. Once consumption gets more than a quart or so between changes..you can contemplate the real fix... or start pouring anything with the word miracle into it.(grin).

Great little car.. Best of luck!
