I have a 2000 ex that only once in a while when you start it up it sputters then dies. To keep it running you have to hit the gas and normally it will be fine ( this may have happened 3 times in the last 1 1/2 months but today my wife said it did it again and would die as soon as she let off the gas. So she had to hold the gas at a high idle for 2-3 min then it finally idled?? and now it starts right up fine ????? Any Ideas!!!!

IAC Valve.

Same story with my 2000 V10. But it was complicated by a wrong K&N filter. Thanks to Lordco in Penticton British Co.lumbia for selling me a K&N filter, labeled for a 5 ltr Mustang...that I returned only to have them insist it was the same for the V10, dust was getting by the seal and dusting everything beyond. The IAC has a little piston exposed to the airflow. It got gummed up and slowed and finally stopped the IAC from operating.

 

What is the IAC valve and where is it???
my guess it is right after the air filter but why guess when you guys can be such a help 8*)
thanks

The IAC is the Idle Air Control valve also refered to as the idle air solenoid. It regulates the air flow through the back of the intake manifold at idle.

It appears as a shiny cylinder about 1 inch in diameter by about 3 inches long mounted in the middle of the back of the intake manifold. If you stand at the front right bumber and look past the yellow transmission dipstick handle.

It's a bit awkward to get to but is a 2 bolt, one plug re and re.

I've posted a pic in my photo gallery about 20 minutes ago but it hasn't shown up yet. I'll post the address here once it appears.

For whatever reason , the 1 photo gallery I made with the photo of the IAC didn't get posted. So I've added the pic to the end of my main gallery at

ok thanks for the help
I changed it and so far so good
But I do have a K&N filter and it seems like people here are saying it is letting dirt through which is what caused the IAC valve to go bad and I should put the stock filter back on
Is this true the stock filter is better than the 240.00 K&N???
should I change it back???
Thanks
Brian

 

I've run the stock paper filter when I've got the K&N filter drying after a cleaning. On the same run from the house to the next town down the valley and back (about 90 kms), I don't record any difference in mileage. Performance gain can be measured only with a dyno. And if I consider the number of kms I drive when the filter is nearing a cleaning I'll bet I'm using more gas as the engine is trying to suck through a muddy gooey mess rather than a dry filter.

I think they are over rated. Also cleaning the oily mess every 10,000 kilometres (I drive in dirt) is no fun. My mechanic also said they will let more dust through than stock. But it's almost irrelavent as the particle size either one lets through is so small (<20 micron?) that, if you change your oil regularly, it has no impact on the motor

So I've gone back to the stock filter. I can also buy 5 of these for the price I paid for the K&N...7 if you count the K&N cleaning kits. By my calculations thats about 100,000 kilometres.

I dunno. It's like wearing a ball cap with the Nike slash on the front. It'll still block the sun without the logo.
