View Full Version : Idle
My car generally idles like a bag of shite until it's warmed up, sometimes even stalls when I stop for traffic lights etc. It's always been a bit lumpy from day one but seems to be getting worse, I thought the service at the weekend would've helped cos I got them to clean the air filter, fit a new oil filter, oil change, new plugs etc, but doesn't seem to have helped. Anyone else had this problem and how did you sort it?? I've heard a new idle control valve could sort it but with me not being very technically minded I don't know how this works...
There are so many things which can effect this, one thing to try is the ISCV(Idle Speed Control Valve), give it a good clean wiht carb or brake cleaner and see if that sorts is, also a bad earth ont he spddeo cable can contribute to it.
Do a search on chavosport, cropped up loads of times
Thanks mate I'll try the at the weekend, where in the engine bay is the ISCV, I've had a look for this before but can't see anything that's obvious (on the Peugeots I've had in the past it's a big screw at the front of the engine bay so easy to find)
Cheers

IIRC on teh valver itsat the front of the block somewhere, not 100% sure tho
Front of engine, right hand side in front of air filter. plug in top of it.
Just reading on chavsport, could be the fact the engine has kent cams and a remapped ECU by Hill Power, I know tuned cars do suffer from idling issues, I'll try cleaning the ISCV and if this doesn't work I'll replace it and if still no luck I'll try and live with it, it's not a mojor problem, just have to warm her up for a couple of minutes in the morning before moving off, it's smooth after a few miles of driving and the oil has warmed up....
i know that aggressive timing of the cams will make it stall mate....but i will see it at the FCS...richy is the man to ask about stalling.

Just time them less agressively?

Here is a list of things i had to replace to solve my stalling problems.
Map sensor
ISCV
Lambda Probe
Ignition Coil
HT Leads
Spark Plugs
Coolant temp sensor
Air Filter
Fuel Filter
and some Injector cleaner
Cheers Northy, if you could have a look at the FCS that would be spot on mate. It doesn't stall every time I stop only occasionally, most of the time it drops to about 500 rpm and then shoots up again, and repeats this until it's warmed up and then it smooths out at about 900 rpm
Cheers for the advice fellas

Its probably just the idle control valve sticking slightly or a build up of crap in the throttle body. Giving the inside of the throttle body a clean would be the first job to do as its quick and easy.
The cams probably will be playing a part in rougher idle as well though.
