Coilpack question

[Ricardos]

Ok so today out the blue the Clio drops to 3 cylinders 2 miles from home. After checking the plugs (none black) swapping HT leads, checking the injectors it turns out the coilpack had failed. Luckily I had a spare genuine Renault 1 so I swapped it and all is fine, just to mention the faulty coilpack was non OE.

Anyway my question is the EML light has been on and off over the last 2-3 weeks so i put this down to the decat pipe. Is there a chance it actually might have been the coilpack breaking down to the point today where it completely failed? When it was running on 3 the EML light permanently flashed.


Ive since done about 30 miles and all is fine, seems to run better and MPG seems to be better too

 

[mad in general]

I am no expert but I believe that when misfiring the EML should flash, It would probably also come on when the lambda sensors detect quite a large amount of unburnt fuel passing through the exhaust system.
