Eml light flashing and rotten egg smell

[Clio182mike]

Coming home tonight and the eml starts flashing and a horrible stink of egg. I have read up and I think I know what's happening but just wondering what order I should go when looking to replace parts? Will plugging it in tell me what is failing?

Fuel injector misfire and your cat will be getting hot.

I've got a new injector so i will have a look later and let you know.

So.... attempted to have a go at fixing it tonight and did the screwdriver to the ear test on the injectors and all 4 are clicking. So i checked the plugs and none are sooted up. Upon starting the engine the idle turns to lumpy immediately and the light starts flashing. Going to plug it in to a Delphi tool in a little while when it turns up.

Do faulty injectors still click?

Yes but the spray pattern can be weak.

Unplug the connector on them one by one and see which one doesn't make much of a difference to the idle.

Pardon my ignorance but can the cat flood if there is a weak injector?

I wouldn't think so.

We got a code df110 but couldn't find anything to say what cylinder. If the injectors are all clicking will checking the resistance of them be pointless?

Could do, but doing what I suggested will find the faulty one pretty quickly.

Will give it another look later. Might pick up some new leads and plugs this morning just to refresh anyway.

 

[Clio182mike]

Thought I would try unplugging the injectors one by one as suggested but all 4 gave a big drop off. So not sure if it's an injector?? I will do the leads and plugs then go from there.

I did the resistance test on the injectors. All said 14.7 except no.3 which was 10.2 so changed it and it worked 👍 i suspect there is still some unburnt fuel in the cat as it is still a but eggy. Needs a blast up a12 and back I think. Thanks for your input
