when i have noticed this it is only wheni first start the car . cant recall anyother times during the day. the rpm's will go down then come right back up to normal.. it sounds like its about to cut off but it never does..

then whenever i start it during the day it is fine ... can anyone help ?

 

maybe somethin regarding ur fuel line, or air intake. my car does something a lil similar. only my car starts off usually with a high idle usually between 1500-2000 and then after i start off im good for the rest of the day, unless i let it sit for hours on end the whole day. nothin to worry about i figure, specially since it only happens 5 seconds out of every day...

 

it could be your fast idle thermo valve, located on the tb.

 

what year is your accord? 90-93? If it is...then i'd recommend changing the idle air control on your intake manifold. I had the same problem, but mine surged from like 1000 rpms to 2000 then drop again. I just changed both controls on the manifold, didn't know which one exactually was making it do that. It wasn't my TPS sensor though because i replaced that first.

Hope this helps!
Good luck.

Edit:

Sorry i didn't recognize your name right away...this stuff probably doesnt pertain to you.

 

i have a 1997 accord lx. yea my car also starts of at about 1500 rpm when i first start it.. but in a couple minutes it goes back down to the regular and thats is when it will start to **** up.

 

usully does that from engine fast Idle to high. If i'm correct or vacuum leak. Check hoses and check your Idle.
