[Paul R]

Ihave a clio tce and every so often i get a random hesitation/missfire in the range of 2000-3000rpm, i dont run the blow off valve just the wastegate, i have tried to find any problems but found nothing its very odd any thoughs are welcome

bump, this is slowly getting worse now

Coil pack, pretty common on all d4f engines

 

[Paul R]

what is it about the coilpack that causes this? and its not all the time either

 

[Sean6545]

Is it a hesitation or a misfire?

 

[Paul R]

feels like if you hit the limiter just not a harsh so a missfire really

Wrong spark plugs make the tce run like poo.
