after my exhaust and intake were installed the idle dropped from 750rpm to about 550rpm idle and 500rpm in drive....is there a way to *correctly* raise the idle ??

I also read about the "plugs" for the throttle blade air hole for '99-'00 trucks to correct the idle flucuation....would this correct my problem or only make it worse ??, could I "test" this by putting a piece of tape over the air hole at idle ??

 

Ls1 edit can take care of your problem no prob.
or you can just press the gas to raise the idle!

 

Edit isn't an option right now and would kinda like to find a better solution than the "redneck idle adjustment"

 

Lol...you pinned me! Im a redneck! haha.

 

there is a little screw on the throttle cable on the side of the TB. just screw it in a little to raise it. or drill the TB blade
