Ever since we have had our +4 from new we have had a slight hesitation on accelerating but have never cured it. I changed to a K&N filter the other week and think it has made it slightly worse. I have the full AR manifold and exhaust and Clubsport tune but that didn’t make any difference. The other week I held my hand over the air inlet and it didn’t make a bit of difference to the engine so guessed it was getting air from somewhere else and then found inside the air filter housing I could see daylight around the outlet pipe so have sealed that up but made no difference. Haven’t had a chance to play anymore as away now so wondered if all you good people had any ideas.
