just wondering why at start up my idle is around 1500rpm but after driving a bit and coming to a stop at a signal light it is around 1000rpm.
Also notice that during initial startup and putting into 1st gear, the car bogs when i take off.
Any ideas? s14 w/ redtop

Car idle at initial startup will always be high (warming up cycle). it will drop after you warm up the engine a little bit, and ultimately hitting the normal operating temp (750ish rpm idle). i thought this is more like a fact wasn't it?
About your second question - I thought it has something to do with the ... initial startup injector (I can't really recall on top of my head).

you might wanna try cleaning your iacv on the intake manifold.

spray carb cleaner thru the filer? or spray into the throttle body?
