Re: 93 Honda accord Code 14
The only times I've heard of a car throwing a code 14 was when the iacv was bad. If you test it it should test bad. Test across the terminals it should be 8-15 ohms.
You can either pull one from a junkyard or get one off ebay if you don't have a lot of money.
To find the vacuum leak you can get a can of carb cleaner and spray it gently around the area you are hearing the leak at. You will notice the idle of the car change when you hit it.
