Engine rpm jumps idle - Saxperience

steffeen · 27th February 2018, 10:04

Hello Saxexperience
I have a Citroen Saxo VTR 1,6 8v I have made for road rally, but i have an engine problem which i cant find the reason for.

When the engine is at operating temperature according to the car it will start RPM jumping from around 600-900 rpm and is close to stalling.

It's only when the engine is at operation temperature, and not when its cold. The fan blower is always at max when it happends.

I have tryed changing air filter, oil, oilfilter, timingbelt, waterpump, thermostat, charging battery and so on..

Any ideas where to look and what to try?

There are dozens of threads coming up when using the search function and typing "idle control valve"

On the throttle body, black thing held in by two bolts.

I tried cleaning, taking it apart, replaceing the spring etc but nothing fixed it. Bought a new one in the end.

But some ICV is priced around 150€ and some around 10€?

I've ran the aftermarket £10 ones for a few months without issue but eventually replaced it with an OEM peugeot one.

Can't remember for the life of me, I went through my ebay and amazon purchase history and couldn't find it. I was just a cheap one around £10 that had a two year warranty.
