Hi guys, well let's start this off by asking someone for some expert advice!

I'm having issues with inconsistent idling! Shoots up and down like there's no tomorrowWhen I stop at a stop street I have to stay on the brakes as the car keeps pushing forward.

What could be the common causes of this as I am now completely LOST. It's annoying and let's not mention fuel...

Any advice would be appreciated.

Thanks

Do you have the MES software to look at engine parameters?

Have you tried cleaning the inlet control valve?

Without knowing how old your car is, that is often a symptom related to the inlet plumbing.

Either the air control valve is dirty/sticky or there is a hole in one of the little control air pipes around there.

I did a temporary fix on my Renault by locating the hole (use a spray bottle with water in it - spray around and wait for the engine note to change- do one area at a time, keep at it and you will track the hole/split down) by using gaffa tape while I waited for the replacement pipe - or you can use fish tank plastic pipe for a temporary fix.

If it's the air control valve, you can clean it out with brake cleaner. Give it a good dosing followed with draining. When the brake clean runs clear you are good to go. You can test the air valve with a 12 battery - it should open and close fully. If not, it needs cleaning. If it doesn't move at all, it may be toast, but they are pretty tough little items.
