accord idle problem

[ghallis05]

i recently ran into a issue with the idle on my 96 accord, i found a thread that the subscriber said he found the problem to be his motor was firing a complete 180, i'm not sure what that means, but his original problem is exactly what i'm going thru. if someone can explain that firing 180 thing i would appreciate it.

I also do not know what 180 means, but he probaby meant timing.
Some accords have idling issues due to EGR problems. Try to look into this link as well:

clean the egr, check for vacuum leaks, change the plugs if they are old, possibly a dirty IAC.

the engine running 180 out means it is 180 degress off. I am guessing this is refering to the corelation of the number one piston at TDC (top dead center). Think of the crank's travel as a circular path. There are 360 degrees in one revolution. To me, being 180 off is when the number one piston is at TDC, but the cam is at the position it should be at when the number one piston is at the bottom of its compression stroke. So basically the cam and crank are out of sync by 180 degrees or half a complete revolution. This is why it is so important to have the crank at TDC when messin with timing belts and other critical engine components.


I had an idling prob with my 92 accord, this is what I did and it worked and cost about 3 bucks.

1.) Find your IAC (idle air control valve) and the fast idle thermo valve.
2.) Rap on both with the handle end of a screw driver while the engine is idleing.
3.) If your engine settles at Idle while you tap on them, your problem probably lies within the IAC and fast idle thermo valve.
4.) When the engine cools (coolant runs through both valves so it may be hot), unbolt the IAC and the fast idle thermo valve and replace the o-rings where the valves bolt onto the intake. The o-rings are formed, so you will need to get them from honda, and no, silicon will not work.
5.) While you have the valves off, you might want to take the top plate and the bottom bowl off on the fast idle thermo valve (use an impact driver or grab the bolt heads with vice grips so you don't strip heads.) and see if the valve is sticking (push it, it should be springy) If it is stuck, replace it.
6.) Put it all back together and start the car.
7.) Watch for coolant leaks and keep an eye on the temp gauge (sometimes air gets trapped in the coolant lines).
8.) If that didn't fix the idle, or tapping the valves with a screw driver didn't temporarily settle the idle, take the thing to a dealer (I know, but sometimes its better than buying parts you don't need).

Hope this helps....
