ED idle problem

[jspec civic]

Help!!

When the car is cold the rev sits low below 1k rpm, after the has been running for awhile it starts to rev up 2k rpm?

engine is a carby

What do i need to check?

thanks in advance

sounds normal?

revs bouncing at all? does it idle so low that it stalls?

[trism]

any mods to it?

that doesn't sound normal..rev does bounce

and no car doesnt stall at all..

when it starts its normal but when its hot it bounce up and down between 1.5k and 2krpm

no mods

do carbys have a IAC?

sounds like a faulty or dirty IAC.. give it a clean with TB cleaner if it has one.

i think ED's have a cold idle adjuster and warm idle adjuster. it used to happen to me.
its one of the screws that adjusts the warm idle(wen ur engine is warm)
so next time just turn one of the screws anticlockwise and if it doesnt lower the idle its the wrong screw
