Hi all. My coupe drives beautifully, but if it sits idle, it's not long before it conks out! It idles for a short period then goes off. So sitting in traffic, handbrake on... if i'm not revving the engine, it does turn itself off.

Any ideas what it could be? It drives fine, not spluttering or anything like that.

Kind regards

Matt

What is the idle speed when warm? I'd suspect a vac leak, but it'd be difficult thing to find.

I presume that spark plugs and air filter are relatively new?

Based on what you have stated; check the Idle valve, process well documented on here. Failing that, check the fuel trims

Thanks guys, I will first check that Idle Valve.

Hi all. Ok I bought a new Idle Control Valve, replaced that, was easy to do. Car seems to be fine now when cold, around 1000 revs, but once warm it struggles if i'm sitting in traffic and I have to keep my foot on the pedal, as it drops too low and conks out! Annoying.

Any ideas what it could be?

MAF Sensor? Air Filter?

Kind regards

Hello? can anyone help?

Thanks

Hello, any ideas anyone?

A difficult one Rizzla guessing from afar. Some years ago I had a similar predicament turned out it was my doughnuts all fine when cool, when hot different story, as you know things swell up and cause leaks. When replaced the old ones looked ok but when pressing them they were pretty worn & cracked. It’s just a matter of finding that leak. Possibly

Hi. Do you think this could be an expensive fix?

Hi. I've replaced the Idle Control Valve myself, no different... still conks out if left stationary when warm.

Can you give me more info about Fuel Trims? I have no idea about where they are located and what to look for. Thanks.

PM'ed you
