idle problem

[zmonster]

what's up guy's? i need some help on this one. i have a 1994 z28 lt1 and whenever i start her up she idles high and then goes real low like its going to die and then it runs fine. i don't know if this a sensor or what.
thanks a lot.

i dont quite follow what your problem is. does it idle low for an extended period of time and then stops, or does it only do this at start up for a moment?

it only does it when it first starts up. and on top of that i tried to start it today and i had to crank it over like 15 times before it would start.
it would turn over real slow like it was trying to start and then i could here this suction sound or something and smoke would come out of my air filter. after i got it running it was fine.

Have you changed the fuel filter?
