When I crank my Accord ( Cold engine )the RPMs go to about 1000 RPMs , then when the engine warms up it revs up and down , up and down, by itself .
Any hints or tips ?
Thanks

Sounds like a typical vacuum leak. Take a gas torch and run it underneath the car WITHOUT LIGHTING IT and if the engine begins to rev higher you have a leak in that hose.Otherwise, there are a lot of things it could be, read prior idle related posts which may give you some other ideas.

 

why don't you just go to the DIY section and read up on the post ,,,,,, surging idle

 

[:@]Yup, Sorry I did read about it now that I located the search button ...
For us newbies the search button sometimes is hard to see, remember we are not used to the page.
Is there a way to make the Search button more visible and more user friendly ?
Thanks for all the info guys

 

I have pingpointed the Problem and fixed it.
My fast idle valve was totally corroded .
The botton nipple on the valve, where the hose carrying the antifreeze connects to , broke off and clogged the hose completellly.
I have replaced the Fast Idle valve and the hose.Problem solved.
Thank you For the instructions doing a search on Idle.
