Had a Service recently.  Changed all the plugs filter  and oil. Engine management  light was on . It was cleared after service . It came back 3 days later .

Hello, 

Welcome, and thanks for joining.
We take it the EML was on, and you then decided to change the plugs in the hope that that would permanently cure the problem. 
When you say ‘it was cleared after service’, do you mean the light went out on its own, or did you get it reset? 
Investing in a diagnostic check to establish the root cause is the way forward, otherwise you will end up throwing all sorts of parts at it. 

Kind regards,

Gareth.

Last bit of advice still stands then.

I agree with Gareth you need a diagnostic check to see if any fault codes flag up
