the idle prob sounds like a senor or iacv to me but maybe im wrong cause ive had the jumpy idle in three different cars now.

it doesnt throw a check engine light and the buld in it is good cause when u turn your ignition all the lights in the dash turn on for a sec some stay on till u start it.

im pretty sure that if it was all of those sensors then you would throw a cel but i check to see if the h23 a has a vacume leak by spraying some carb cleaner around the engine bay and if it idles up then you have a leak some where and just keep doing it till you narrow the leak down.
