Rough idle

[MrMark]

My idle seems to be slightly rough lately. it usually stays between 500 and 750 rpm, when idling after its warmed up.

when i throttle it to 1000rpm for example, it's nice and smooth.

Do you recon new sparks would be the best bet, (originals are still fitted, mk2ph2 2002 45k miles)

or should i take a look at the ICV?

thanks, guys.

It won't be idling at 500rpm its supposed to stabilse at 750 or so th rev counters not to accuate at low rpm so don't work off that you'd kno if you have a 500rpm revs.

New plugs sould like a good idea they can get dirty.
Also check your throttle body is clean as they can get dirty and cuse problems.

You don't have an idel control valve.

throttle body is fine, that was the first place i looked.

new plugs it is then. i dont have a service book, so i dont know when they should be changed. but they are not expensive.


never knew that it controlled the idle, i thought it had an icv.
