Citroen C2 1.4 petrol VTR 2005 starting problem

[ovouti]

Hi again, ill youse the same post for differend problem at the same car.

What is the common problem when the idle is bit rough? It sails under and over 1000rpm, sometimes almost feels its going to turn off. Sometimes also when i start the car feels like i need to press gas little bit that it starts well. Would it be throttle body? No warning lights or anything. Thanks for answers!

You could clean inside the throttle body in case it has a carbon build up on the throttle body/plate area. Carb cleaner spray will work as well as wiping out with a rag soaked in white spirit (paint brush cleaner).

Could be a vacuum leak.
Check the vacuum line to the brake booster.
Spray carb or brake cleaner around the joints of the inlet manifold.
Check operation of purge valve.
Vacuum leaks only tend to effect idle. Engine usually runs fine otherwise.

Didnt find any vacuum leaks, sprayed brake cleaner everywhere. It dont do it always, sometimes when i restart engine it does it, i have to little bit gas for a while and it goes away. And then it works just normal when idling...Purge valve is also new one.

sometimes when i restart engine it does it,

When the engine is hot? Does it do this when the engine is cold?

I think its more when its hot.

[ovouti]

When i start engine cold, it works just fine. And when it heats up works just fine also, but when i shut down engine and try to restart when its hot its very rough start or dont start at all, when its starts the rpm will bounce back and forward, it stops and works fine after i press hard on gas for 1-2 seconds.

[PaulC5]

Possibly a fuel problem. Are any fuel lines near something hot ?

I am suspecting a leaky injector.

When driving its fine, but when stop for lights the rpm will bounce up and down hard, if i press gas hard once it stabilizes and then same again driving fine and stop same thing happens...
