Are you waiting to start until the FP stops running?

Yeah, but I've done it both ways, oddly enough, it seems to be that once i let ir run and shut off, it doesn't want to start...but oddly if i jump from full off to start immidiately, it will start faster

I usually wait for the gauges to do their thing before I crank unless I am in a hurry. But either way I don't notice a difference

my gauges dont do a thing. they just...sit there..and look at me. so i never wait for their thing to happen. but there seems to be a significant difference between fast and slow.

Umm, IAC? And how would I go about doing that? Never heard of an IAC.

That'* your Idle Air Control valve. When your throttle plate is closed and your foot off the gas, it'* what lets a small amount of air in, which it varies slightly to get the desired idle speed.

If your car idles fine when running, I wouldn't think that would be the problem. Still, it'* free to remove and clean it. Can't hurt to try.

A search should turn up plenty of info on that.

ok, is it removable without removing the entire throttle body? i've done that before on the LN3 on my Electra and nightmare doesn't even cover it. just was not fun. does it screw in or something? I know what you're talking about now at least.
