I have a 1998 caddie(catera), it had to get a new engine but before it got the new engine, it was acting funky(it may have been an entirely different thing, since the engine head was cracked before)...anyways, when I start up the car and haven't driven it in about 4 hours, it starts up perfectly with a little delay, but if I have driven it recently the RPM's go a bit wild, not starting unless I keep the gas on it, and eventually it will pick up(however I have to keep the gas on, not letting go when I brake) and sometimes the RPM goes up to 1 or 2 if I put it in park after having driven it for like a minute.
