172 Misfire clears when thrashed..

[Luke 172]

My 2001 clio doesn't like sitting at any speed for more than 30 seconds.
Just judders at any speed 40-70mph in any gear.
That said it clears as soon as I boot it. Confused I am. Thought misfires are misfires what ever you do, also my idle is 600rpm and lumpy like its running wild cams!?!?

I'm sorry but this has been covered so many times.

Use the search function.

Get it plugged into diagnostics.

It'll be injector, coil pack, leads or it doesn't have the correct NGK PRFE-6 plugs
