Idle electric motor question

Should the electric motor that sets the idle move to the idle position quickly when the throttle is released? Ours takes about 4-5 seconds at least to go back to idle from higher revs, Ive sprayed some crc in there but still takes a while to return.

Mine does the same! It is very annoying, I've actually replaced the IAC motor but it made basically no difference. Anyone have any idea what is going on here.....

Ive noticed mine does the same, takes 4-5secs. I presume that is standard.

Re: yeh

Mine used to do that constantly, got a bit dangerous while braking cos it wants to keep going. I fixed it by changing the throttle cable and resetting the computer and doing the "learn throttle position procedure" and it fixed it up. You probably wont have to change ya throttle cable cos mine was ****ed, but try resetting the computer and doin the throttle position procedure.

idlespeed control

i actually dismantled and repaired my isc, dont spray crc down the thing, you will bugger it. It is meant to come up when you open the throttle and then gently return it to idle speed, although it will seem like it is fast doing it , it is doing it. Open the bonnet and open the throttle with your hand while the engine is running, the plunger should go up about 5mm, let the throttle go and it should smoothly retract when the throttle touches it.
there is a proceedure to reset the throttle position, mine used to do it but after resetting it it has been fine. I do have it all written down somewhere.

Re: idlespeed control

I replaced my throttle cable a while back also. Yeah this bugs me too, it is kinda dangerous because it does fight the brakes a bit. I have set the idle a bit higher than stock because the stage 1 cam is quite rough at idle and the computer hasnt "sorted" it for me. I understand how it works but it just seems to work too slowly.
