Clio 182 flashing emissions light

[adamh84]

As above I have a flashing emissions light once the car is upto temeprature. I have checked the fault codes and it has so far come up with cylinder 1 miss fire , ive had cylinder 4 missfire , and now ive just had random or multiple missfire P0300.

The car drives fine, it doesnt sound like its missfiring... I have just bought a new cat as this was missing form the car but im still waiting for the rear lambda sensor to come so at the minute it has a lambda sensor in it, but not connected (different manufacturer) . I know this would cause the emissions light to come on but could this cause the flashing emissions light and random missfire fault codes? I have done some searching and from what I have read the rear one doesnt affect the fuelling? The car once upto temperature does give off an eggy sort of smell? I just dont want to keep spending money on this car guessing at parts and replacing them i have done enough of that already.

I do have a diagnostic lead but it is the ross tech vag-can so just works as a generic obd2 lead but it will let me look at some live data

Any thoughts on this with other peoples experience would be appreciated.

What have you replaced so far?

Any signs of tracking or arcing on the HT leads? How old are the plugs? How old is the coil?

I've replaced the throttle body , the accelerator pedal and the crank sensor so far . The 1st 2 where due to a different fault but it didnt cure them, so i swapped them back and it seems to have gone lol, I was getting fault codes relating to the throttle and pedal potentiometer. But I didnt have the problem with the emissions light flashing . After a while it would come on due to the rear not being plugged in but it wasnt flashing and the car didnt have an eggy sort of smell.

I have also replaced the inlet manifold gasket but this did mean unplugging the coil unit and the leads at the coil side . I have rechecked these but all the connections seem good. I dont have any history with the car but I do know it hadnt ran for maybe 18months prior to me getting hold of it. ( the car was going to be scrapped unitl i bought it due to cutting out 1 day and not being able to get it restarted. It turned out to just be a fuse for the ignition relay.)

TBH I havent looked for any arcing on the leads but i will do tomorrow , I just didnt want to go out and buy a new coil or leads and plugs and it still not be the cause of the problem

When i had that flashing mate it turned out to be an injector

All fine now i borrowed a code reader from a garage and it just shows that the rear lambda is missing , cheers for the reply though.
