When my ’96 Honda accord, 4 cyl, 2.2 L manual tranny, has been off for
a while, upon startup it will "surge" between 1k and 2.5k RPMs. It
will do this for about five minutes before leveling off to a normal
idle. Once the car has warmed up, I can turn it off, come back 15 mins
later and it will idle normally upon startup. Its only after it has
sat off for extended periods of time. Anybody experience this before?
Is this a defective sensor? Also, I have a high flow, short ram AEM
intake, not sure if this makes any difference. Any advice would be
appreciated. Thanks.

maybe sticking or leaky fuel injectors? try running a couple tanksfuls with
Techron injector cleaner.

check coolant level inside radiator, not expansion bottle. needs to be
full to the top.

You also need to bleed the air out of the cooling system. See this diagram,
http://tinyurl.com/2osqo8, for the location of the bleeder bolt. It should
be part #12. With engine cold, loosen the bleeder bolt and add coolant
until there are no air bubbles remaining in the stream of coolant exiting
from the top of the bleeder bolt.

Let us know if this helps. If not, then there could be a problem elsewhere.
