Hello there everyone, my 1998 Camaro LS1 is idling at 2800 RPMs and I have replaced the intake gaskets and the idle air control valve, any ideals why its idleing so high? Thanks for all the input.

 

you got a vaccum leak somewhere and its big. try doing this... get some really soapy water and put it everywhere theres a hose and watch for any bubbles. theres also a thing you can buy that injects smoke into the system and makes it really easy to find.
