Cold start missfire

Captain Carling · 01-26-2023, 11:42 AM

Hi all, I have a problem where if the outside temp is around 0 degrees, my M4 will missfire as I try to pull off and then goes fine after say a minute or so. It happened last winter then was fine all summer and reappeared this winter.
Any ideas what it could be.
It's a 2014 M4 running stage 2 UK.
Cheers

What codes do you get?

Do you have open filter intakes?
