Engine management light

[babyface]

Have recently acquired a solid EML on the clio 172.
The car has a lumpy idle, pops and bangs alot at high revs and has blue smoke.
This has only just happened recently. (1 week)
Just as a quick check list (dont have a code reader atm)

- Both lambda sensors?
- Spark plug
- Ht leads
- Coilpack
​

Are these the more likely problems to why the car is running rough.
(the car has had a remap by ktec)

thanks

Cant help with the eml and rough running issuses but blue smoke normally indicates worn piston rings, is ut using much oil?

Just resets lugged a code reader and reset it and the light has gone, with no blue smoke etc.. Flagged up with a lambda sensor. Could just be minor fault. Will post again if it flags up again.

No oil usage, no change in mpg.. Just had lumpy- er idle runningg a little rich.

Is the blue smoke from exhaust or is oil dripping onto manifold as a result of possible rocker cover leak?
