When I start my 91 ls 400 it idols right for some reson then after the engine warms it goes down... what is wrong wit the idol control ... 1 Luv

 

That's normal behavior, unless the warm ldle is too low and the engine stalls or runs roughly.

Idol problem? I thought this might be a thread about bad singing.

 

I don't think there's anything wrong with your idle. The engine idles higher when cold to warm it up to normal operating temp so the thermostat opens quicker. The normal idle is 1100-1250 cold and warm is 550 - 650. What does yours idle at?
