Hi Guys,

Im hoping you lot can shed some light on this problem. Basically I have an N reg 306 Petrol XSi and it has developed an annoying fault. Basically it seriously lacks power and in the morning to keep it from stalling I have to put my foot on the clutch and accelerater (ie put a lot of power down) to stop it from stalling and start going a bit. It literally "chugs" along and it can be driveable after a bit, but when you try to use the 2 -3,500 RPM power band in most gears, all the power just goes, goes so bad I darent try and overtake a slow car on a long open straight.

Any ideas?

Check all the usual suspects first of all - plugs, leads, dizzy, AFM (if it has one) etc.

Idle Valve - Common problem with the 2.0 8v.

My 306 was the same, although I sold the car before actually fixing it!!

You may need to register, but this thread may help

totally agree with this diagnostic, my friends 306 XSi 8V did exactly the same thing. My old 205 1.6 GTi also did this but at the time I had no idea what the problem was and I traded it in as I got sick of swapping parts in the hope of curing it.

ok guys, read the thread. Thanks for that, but where and how do I fix the idle valve. Also I get the smell of burning oil sometimes as well if thats helps.

Any pics of under the bonnet?

I assume its similar to the 205, so the ICV will be on top of the manifold. If so, its a metal cylinder which has connections to the manifold and oil filler IIRC.

Its held onto the manifold by a rubber holder thing.
